In the startup world it is a huge economic advantage if you can prototype an idea in days that would have taken months or years. The tradeoffs are acquiring technical debt but we seem capable of resolving that after the concept has found product market fit.
As far as I can tell, most startups resolve their technical debt by failing, and the majority of the rest resolve their debt by being acquired by a company which replaces the original service entirely in 1-3 years because it's too hard to integrate as-is.
