Have you ever stopped to think about the real impact a person can have on the history of technology? That's right, William Gates is exactly the kind of figure who shapes generations. When you use Windows, open a file in Excel, or work in the cloud, you're literally using a legacy that Gates helped build since the 1980s.

Born in Seattle in 1955, William Gates had contact with computers at a very young age, still in his teens. Along with Paul Allen, he started tinkering with programming and even tried to create Traf-O-Data, a traffic data analysis project. It wasn't a big commercial success, but it was there that Gates developed the technical mindset that would define him later. In 1973, he entered Harvard, but only stayed for two years. The opportunity to work with software for the early personal computers was too great to pass up.

Microsoft, founded in 1975, was the turning point. Initially focusing on programming languages, but the big breakthrough came when they managed to partner with IBM. Gates and his team adapted existing software, created MS-DOS, and, most importantly, kept the licensing rights. This allowed for rapid scaling and distribution to multiple manufacturers. In the 1980s, came Windows and Microsoft Office, products that literally defined how we use computers to this day. This market dominance made Gates one of the world's richest billionaires.

But here’s the interesting part: William Gates is no longer as focused on accumulating wealth. In 2022, he transferred about US$20 billion additional to his foundation. Currently, the Bill & Melinda Gates Foundation distributes around US$6 billion per year, with plans to increase to about US$9 billion by 2026. He has already made it clear that he intends to gradually step out of the ranks of the wealthiest.

The foundation operates on three main fronts: global health (fighting HIV/AIDS and malaria), poverty reduction in developing countries, and investments in clean energy. This shows a well-thought-out strategy. Gates also created the Giving Pledge with Warren Buffett, encouraging other billionaires to donate most of their fortunes to philanthropy.

In the investment field, William Gates is heavily betting on artificial intelligence. Microsoft has already invested over US$10 billion in OpenAI, the creator of ChatGPT. This partnership allows integrating advanced AI into products like Azure, Office, and corporate tools, creating new revenue streams. Gates believes AI will have an impact similar to the internet or personal computers, potentially revolutionizing education, improving healthcare systems, and increasing global productivity.

Beyond AI, Gates invests in clean energy through TerraPower, betting on advanced nuclear energy as a climate solution. He is also involved in agricultural innovation, food security, and biotechnology. This diversification reflects important global trends for those who follow technology and ESG.

Even outside Microsoft’s management, William Gates remains relevant because he is constantly allocating capital in strategic sectors, participating in global debates on climate and health, and offering valuable insights into the future. For investors, following his decisions can reveal important trends that will impact markets in the coming years. It’s like having a treasure map to understand where global technology and innovation are headed.
