> Enough to build sustain a company of Meta's size?
This is the problem - I'd argue we shouldn't have companies the size of Meta (or Alphabet, Apple, Microsoft, etc.). It's that these companies are nation-state level huge, and operate in a system that continues to demand more growth still, that causes problems like enshitification.
Would enough people pay for Facebook to support a company of Meta's size? No, but that's OK - enough people would pay for it to support a much smaller, customer-focused company, and that would be a really good thing across all of tech.
What's so wrong about just sustaining a certain size/user base instead of endlessly growing bigger and bigger?
