On Curiosity — Sharif Shameem, Lexica
Jul 19, 2025 · 18:35
Sharif Shameem, founder of Lexica, argues that curiosity is the main force for pulling ideas from the future into the present, and that building and sharing demos is the best way to explore AI models' hidden capabilities. He recounts early GPT-3 demos from 2020-2021, when the model had a 2,000-token context window and cost $75 per million output tokens, showing how he built a JSX compiler in the browser, a shopping agent that parsed web pages, and a multi-step reasoning tool called MultiVAC. Shameem emphasizes that AI engineering is more like excavating than traditional engineering, and that researchers often don't know the full capabilities of their own models. He closes by invoking computing pioneer J.C.R. Licklider, arguing that today's AI engineers have a moral obligation to follow their curiosity and share what they discover.
