I don't think I can do it in 1 year. 5 years is perfectly possible.
We live in the golden age of computer science entrepreneurialism.
Venture capital has never been easier to get. The low hanging fruit is largely still unpicked. And, with full remote, hard working highly capable talent has never been easier to hire (hire Europeans, they're overeducated and underpaid).
IMO, not starting a business in the next 5 years would be remarkably foolish.
Just have to write a 35 page business plan, get it reviewed by capable people, have a good idea, and execute.
