Amjad Masad says AI growth may follow overlapping S-curves, not exponentials

Amjad Masad, CEO of Replit, says in an X post that most real-world growth follows S-curves rather than sustained exponentials.

He cites his time at Facebook, where growth that looked exponential came from overlapping S-curves driven by breakthroughs and adoption waves. He argues AI probably works the same way, but says progress does not have to slow and that sustained exponential growth is not automatic. The post offers his view and cites no data for AI specifically.
