I don't think technology is a linear progression towards more and more capital intense businesses.

Software businesses in the 2000-2020 era were famously capital light. Much more so than the technology businesses that came before them. I think these extremely capital light businesses were an aberration that briefly lowered average founder age and now we're just reverting to the mean.

Yes, AI is capital intense, but many of the world's previous technological endeavors were also capital heavy.
