As he applied for colleges before his senior year at Lakeside, Gates tried to redefine himself beyond his reputation as a “nerdy” computer whiz. He spent the summer working as a congressional page in Washington, DC, and became fascinated with the drama of politics. He also auditioned for the school play and earned the lead role. Rehearsing with his castmates gave Gates the same thrill as exploring in the computer lab. He also had the opportunity to flirt with his female costar, Vicki.
Gates decided not to apply to the Massachusetts Institute of Technology (MIT) because he didn’t want to be surrounded by people with similar interests. He crafted different identities for each of his applications: emphasizing his software experience with Princeton, his interest in drama with Yale, and his interest in law and politics with Harvard.
In December of his senior year, Gates was approached by the Bonneville Power Administration (BPA), the federal utility responsible for generating and distributing electricity across the West Coast. The BPA asked Gates and Paul Allen to help develop a computerized system that balanced fluctuations in power supply with demand. With the support of the Lakeside headmaster, Gates’s parents agreed to let him skip the winter trimester in order to take the job. Working with professional engineers helped to hone Gates’s skill as a programmer and reduce the arrogance that came with being the most talented programmer at his school.
In the spring, Gates was accepted into Yale, Harvard, and Princeton. He worked up the confidence to ask Vicki to prom and was heartbroken when she rejected him. At the annual senior skip day, he tried LSD and enjoyed it until he remembered that he had a dental appointment the next day.
After graduation, Gates spent the summer at BPA headquarters in Vancouver, Washington. The adult programmers he worked with encouraged him to skip college and go directly to graduate school in order to develop his skills. Allen believed that he should skip higher education entirely so that the two could form their own computer company in the vein of the Digital Equipment Corp. As they lived, worked, and spent all their free time together, Gates and Allen argued more often, and Allen ultimately left the Lakeside scheduling project and the traffic project in Gates’s control. The two stopped speaking to each other for the rest of the summer but were brought back together by their friend Ric Weiland.
Gates arrived at Harvard University in the fall of 1973, just four years after Harvard took possession if its first major computing system, the PDP-10, which was previously used by the Department of Defense in Vietnam. Boston was a major hub of computing, with institutions like Harvard and MIT working directly with the government on defense projects. Harvard’s Aiken Computation Lab was funded by the Defense Department’s Advanced Research Projects Agency (DARPA), and the lab’s computer was connected to the ARPA Network, later known as ARPANET, which would become a foundational precursor to the internet. The Aiken Lab was run by Tom Cheatham, who gave Gates permission to access the computer, despite the fact that the lab was mostly used by faculty and graduate students.
In an attempt to broaden his horizons, Gates made an unusual request for his roommates: a foreign exchange student and a person of color. Living with these roommates made Gates aware of his personal privilege. He registered for the most difficult math class offered to freshman and passed the exam required for admission. The class was a pure mathematics course taught by John Mather, a legendary mathematician. By the end of the first month, the class dropped from 80 students to 25. Gates became close friends with two classmates, Andy Braiterman and Jim Sethna.
Although most people in the Aiken Lab worked on the PDP-10, Gates was immediately drawn to a smaller, older computer, the PDP-1. The PDP-1 had a better graphics display and allowed programmers to work directly with the computer rather than accessing another device. It was also able to connect directly to the more powerful PDP-10, allowing for complex computing with high-tech graphics. Inspired by the myriad innovations produced in the Aiken Lab, Gates proposed his own independent research project: a baseball game that displayed graphics on the PDP-1 and used computing from the PDP-10 to dictate play. As Gates worked on the project, he became ingrained in the exploratory, democratic culture of the Aiken Lab.
Despite Gates’s success in the Aiken Lab, he struggled to shape his identity at Harvard. While he was the smartest person in a supportive environment at Lakeside, he found himself surrounded by equally brilliant students in a competitive environment at Harvard. Not being the smartest person in the room was a severe knock to his confidence and sense of self. His friends encouraged him to pursue computing, his true interest, rather than pure mathematics. Gates sent out applications and received job offers from computing firms. Paul Allen accepted a job at Honeywell, but Gates decided to remain in school.
In his sophomore year, Gates declared applied mathematics as his major. His advisor described the major as a wild card that would allow him to take courses across the university, given its various applications. As a result, Gates sat in on a variety of classes that had nothing to do with math, forcing him to study intensely in order to make up the essential classes he skipped. In addition to his time in the Aiken Lab, Gates also became an avid poker player, playing in tournaments with other math majors who applied game theory and mathematic tricks to their game.
When Allen moved to Boston, he began to fill an older-brother role for Gates, encouraging him to experiment with LSD and keeping him informed of the newest challenges in computing. Although Allen was still interested in developing hardware using the Intel chip that they purchased in Seattle, Gates believed that they should focus on developing software. Gates attempted to secure a microcomputer from Intel through his Harvard professors, but most were uninterested in helping. In hindsight, Gates recognizes that, at the time, the applications for the microcomputer were so small that it seemed ridiculous to offer one to an undergraduate for experimentation.
In December 1974, Allen approached Gates with an article about a new microcomputer using an Intel processor called the Altair 8800 being sold for less than $400. Gates and Allen realized that the microcomputer revolution that they were hoping to lead was happening without them. The pair decided to write a programming language for users of the Altair and pitch it to the manufacturer. In order to develop the language, they wrote a program that allowed Harvard’s PDP-10 to act like the Altair. When they attempted to sell it to the manufacturer, they learned that others had also proposed their own languages and that the first developers to succeed would win the contract. They also learned that the Altair itself was not complete, and the article that Allen found vastly overestimated the project’s status.
After six months of frantic coding, Gates and Allen, along with a freshman named Monte Davidoff, developed a sophisticated coding language for the Altair. Gates’s conversations with the Altair manufacturers led the group to believe that they were the first to complete the project. In March, Allen flew to meet the Altair manufacturers and demonstrate the code. The test was successful. Gates identifies the code as the first piece of software ever written for a personal computer.
This section of Source Code examines the memoir’s thematic interest in The Importance of Exploration in Education by demonstrating the value of a wide-ranging, student-led education in establishing Gates’s career. In his final year at Lakeside, and his first two years at Harvard University, Gates determined to move beyond the stereotype of a “nerdy” computer whiz as part of his quest to establish his own identity. As a senior at Lakeside, he dropped a math course to take drama and was ultimately cast as the lead in the school play. Gates describes his foray into acting as a “rewarding” trip that took him “out of [his] comfort zone” (178). This anecdote suggests that, although Gates is best known as a programmer, he values other educational pursuits, such as drama, for their capability to push boundaries and expand personalities. This moment also reflects Gates’s increasing awareness of how others perceived him and his desire to shape his personal brand—an instinct that would later prove crucial in his leadership at Microsoft.
In the winter of his senior year, Gates and Allen were approached by the BPA, a major West Coast utility, to consult on their project computerizing their electric system. Although Allen, a college student, was able to take a leave of absence, Gates was forced to ask both his parents and his school for permission. His parents’ initial resistance was overruled by the headmaster whom Gates calls “Few-Rules Dan,” who recognized the potential benefits of the work and “suggested the time could be used as an independent study and count towards graduation” (181). Gates identifies his work with the BPA as an essential steppingstone in his career as a computer programmer, one that led to future opportunities for both Gates and Allen. This anecdote underscores how non-traditional learning environments and hands-on projects played a vital role in Gates’s development, again highlighting the importance of exploration in education. It also reinforces the theme of Cultural Changes in Mid-Century America, as educators and institutions were beginning to embrace more flexible, student-driven learning experiences that emphasized innovation over rigid structure.
Gates’s pursuit of an open-ended, exploratory education continued at Harvard, where he worked in the Aiken Computation Laboratory under the guidance of Tom Cheatham, a professor with “a reputation for giving his students autonomy and letting them experiment” (197). The use of the terms “autonomy” and “experiment” in this passage suggest that Cheatham was willing to let students take charge of their own computer science education, even if, like Gates, they weren’t working with a specific goal in mind. With the freedom granted to him in the Aiken Lab, Gates developed an independent study centered on the goal of “connecting the graphics-capable PDP-1 with the more powerful machine across the room” (204), a project that had not been considered by anyone else at the lab. Gates explicitly acknowledges that the “freedom [of his] independent study” allowed him to “push the limits of [his] programming” (209). He argues that his independent study at Aiken “gave [him] license to explore” in a way that Harvard’s course offerings could not (222). Gates’s experience at Harvard reinforces the memoir’s argument that structured education alone is not enough to produce innovation; true learning comes from unstructured, self-motivated problem-solving. His trajectory also echoes the journeys of other tech entrepreneurs, many of whom found institutional education too limiting for their ambitions.
These chapters of Source Code also depict Gates’s shifting relationship with his future co-founder, Allen, as Gates and Allen moved from high school rivals to business partners. Central to this relationship was Gates’s realization that Allen was a valuable collaborator with his best interests at heart. At the end of Gates’s senior year, Allen “pushed [him] to forgo Harvard” (189). Although Gates initially balked at the idea, readers familiar with Gates’s story will know that Gates did eventually drop out of Harvard. His decision to include Allen’s early suggestion that he not attend college suggests that he believes that Allen knew what was best for their partnership. Gates later affirms this idea when he compares his own “solo-scientist view of the world” to Allen’s vision of “the world advancing through collaboration, in which teams of smart people pulled together toward a common goal” (190). Although Gates now believes that “both views were simplistic,” he acknowledges that “in time his would define both of [their] futures” (190). This passage highlights the theme of The Value of Rivalry in Innovation, as Gates’s and Allen’s differing perspectives on success ultimately pushed both men toward a more balanced and productive vision for their company.
Gates’s time at Harvard also provides insight into his personal insecurities and struggles with competition. While he was the smartest person at Lakeside, he found himself surrounded by other great minds in a competitive environment at Harvard. The realization that he was no longer the standout intellect forced him to confront his self-worth beyond academic superiority. Rather than allowing this challenge to derail him, he channeled his ambition into carving out a niche where he could distinguish himself. This transition highlights Gates’s adaptability and foreshadows his later success in an industry defined by rapid change and fierce competition. This moment further underscores the value of rivalry in innovation, as Gates’s competitive nature forced him to re-evaluate his identity and future path. Rather than quitting in the face of stronger peers, he redirected his ambition toward a field where he could remain at the forefront—computer programming.
Finally, this section of the memoir details a major turning point: the moment when Gates and Allen discovered the existence of the Altair 8800 and realized that the personal computing revolution was already happening. The sense of urgency in these passages reflects the way competition fuels Gates’s drive: “We weren’t the only ones rushing to write software for the Altair” (230). The stakes were high, and the pair had to work quickly to complete their project before another team beat them to it. This moment solidifies Gates’s belief that timing is just as crucial as skill when it comes to innovation. The sense of competition surrounding the Altair project forced Gates to realize that the industry was no longer a small niche of hobbyists—there was now a race to dominate the emerging personal computing market.
