The biggest mistake in AI isn't picking the wrong model It's renting the same compute forever For years, people accepted cloud GPU bills as a normal cost of doing business Every month the invoice arrived Every month the money disappeared Nobody questioned it because that's just how AI worked Until local AI hardware started getting good enough to change the equation That's what caught my attention Not the hardware -> The mindset shift Because once you own the compute, experimentation gets cheaper And every project becomes more valuable The weird part is how many people never stop to calculate what they're actually spending over a year Thousands go out the door without a second thought Meanwhile a growing number of builders are asking a different question It might be renters vs owners
