Bill Gates says the graphical user interface first changed his view of personal computing in 1980.
An early ChatGPT demonstration in 2022 showed Gates a new level of computer intelligence.
Claude Code made Gates rethink how quickly AI could reshape software development and knowledge work.
Bill Gates says only three technology moments have truly stunned him across his long career. The first came in 1980, when he saw a graphical user interface, or GUI, for the first time. The second came in 2022, when OpenAI leaders visited his home and showed an early version of what soon became ChatGPT.
The third came in 2026, when Gates took a close look at Claude Code, Anthropic’s artificial intelligence tool for software work. The last event carries the most weight. Gates knows software better than almost any other field, yet Claude Code showed him a level of machine skill that he did not expect this soon.
The 1980s moment came from the graphical user interface. Before the GUI, computer use often required typed commands. Gates saw a path toward personal computers that ordinary people could use with far less effort.
The GUI helped move computers away from a specialist tool and toward a product that more people could understand and use. The change later shaped the modern personal computer and set a new standard for the way people could interact with machines.
Gates had another major surprise in 2022. OpenAI leaders came to his home and showed him an early version of ChatGPT. ChatGPT could understand questions, produce useful text, explain ideas, and handle tasks through ordinary language. This marked a sharp change from the software model of his career.
Computers had moved beyond screens, menus, and fixed commands. A person could now use everyday language to ask for information or help with a task. For Gates, the demo offered an early view of a computer that could handle parts of work once linked closely to human thought.
The third moment came in 2026 with Claude Code, an artificial intelligence tool from Anthropic. Gates focused on software development, a field close to his own expertise. His reaction showed how much the latest AI systems had changed his view.
Gates said the idea that these systems could become better than he was at a subject he knows best felt almost unreal. Earlier software helped people write code faster. Claude Code showed a system that could handle much more of the actual software task.
A tool that saves time still leaves the main task with a person. A system that can carry out complex software work changes that role. Gates sees software development as one of the first fields that AI may reshape in a major way.

Gates’ approach towards artificial intelligence has become more measured. In an August 2026 piece, he stated that artificial intelligence has made its entrance and advocated for a plan to ensure that the advantages of artificial intelligence surpass its disadvantages. He highlighted areas such as healthcare, education, agriculture, science, and professional assistance.
Moreover, Gates has expressed worries regarding job elimination, cybercrimes, biological threats, and difficulties individuals will have with managing AI systems. He stated in a Reuters interview in September that authorities are still quite behind when it comes to technology development. The Gates Foundation introduced the USD 1 billion program for endeavors related to artificial intelligence in education, healthcare, and agriculture within the next two years.
The GUI made computers easier to use. ChatGPT made computers far better at language. Claude Code pushed the machine closer to actual knowledge work.
That last step may explain Gates’ mix of excitement and concern. Earlier advances changed the tools people used. AI can change the work itself. Software offers a clear example, yet the same pattern could reach law, research, medicine, finance, education, and other fields.
Gates also continues to place major attention on energy. TerraPower received US regulatory approval in March 2026 for its Natrium nuclear reactor in Wyoming. The plant has a planned output of 345 megawatts, with an energy storage system that can raise output to 500 megawatts for several hours.
That focus also matters for AI, since data centers need large amounts of electricity. Gates’ work in AI and advanced nuclear power therefore points toward two parts of the same technology shift: smarter machines and the energy needed to support them.
Why this Matters
Bill Gates’ three technology breakthroughs show how quickly computers have moved from simple tools to systems that can handle complex work. The shift matters far beyond software. AI could change jobs, education, healthcare, science, and business, while also creating new risks that governments and companies must address as the technology advances.
Gates’ three surprises show how his idea of innovation has changed. The GUI changed how people used computers. ChatGPT changed how people communicated with software. Claude Code challenged the old boundary between a computer tool and a skilled worker.
Gates did not describe Claude Code as just another useful product. He described a moment that forced him to rethink what machines can do. For a software pioneer who has watched several generations of computers grow, that reaction says a great deal about the scale of the current shift.
