Bartosz Ciechanowski really gave us a look at what the future of the web would look like. It seems like these kinda pages are the norm now with AI assisted dev, which I absolutely love. Fully interactive pages are so much more intuitive than static ones of the past. He has my thanks for ushering this in as a standard.
AI definitely lowers the cost of building these, but I think Ciechanowski's real contribution is upstream of the code. Knowing what to visualize and how to make interaction teach something rather than just look impressive is the rare part
