1. That confidence and quality is worth the price.
2. We're accelerating at lightning speed now. If you don't spend, someone else will and they'll eat your cake.
We're nearing the point where you could spin up an entire YC startup in a day. That changes the economics of everything.
But is speed of creation really the golden goose here? A few skilled and motivated individuals could also do (and have been doing) that.
Sure, maybe they take a few months instead of days or weeks, but AFAIK, having a product is just a tiny bit of the battle, finding customers, product market fit, and actually growing it is where the gold is so I'd argue that you'd be better off building the product with a $100 day LLM and spend the other $900 on marketing.
AI won't automatically make everybody business gurus and every LLM generated company a unicorn.
Accelerating how much slop you can output? A better model will still produce slop for your feature factory that pumps out software which nobody is interested in buying.
You don't seem like an entrepreneur. Why are you on HN?
YC wants people to build AI startups. You're here shitting on them. Half of this community is. You're all a bunch of old men grumpy at the new tools.
I'll offer my own analysis: if you're not using AI very effectively, you won't have a career in computing in a few years.
