Tim O'Reilly

Legacy & significance

O'Reilly has spent four decades doing the same thing under different names: spotting a technology shift before the industry has language for it, then naming it. 'Open source' and 'Web 2.0' both trace to conferences he convened, and his publishing house has been the technical-literacy backbone for the programmers who built the modern internet, and now AI.

Major achievements & key works

• Founding O'Reilly Media (1978). Built the dominant technical publisher of the internet era, training generations of engineers through its books and conferences.
• Convening the 1998 'open source' summit. The meeting that coined and popularized the term 'open source software' as an alternative to 'free software,' reshaping how the industry talked about collaborative code.
• Coining 'Web 2.0' (2004). Named and framed the shift toward user-generated, participatory web platforms, a term that defined an entire industry era.
• WTF?: What's the Future and Why It's Up to Us (2017). Argued for a human-centered approach to technology and algorithmic platforms, prefiguring many current AI-ethics debates.
