Most startups fail because of no market or money issues, not because of product issues. You can build a wonderful cathedral and pray an empty god in a wonderful desert. Then someone cuts oil supply and the cathedral is not aor conditioned anymore. So go ahead, build 50 products, hope that 1 succeeds. My bet is that 50 will fail and 1 person in 1000 will succeed. But everyone will spend so much money on Nvidia and Anthropic that they will eradicate whatever else is in the world.
