You are being overly negative here. No one said they are doing something groundbreaking. If they were doing something groundbreaking with credibility, they wouldn't be giving away 7% to YC at $2M valuation. All the big AI folks who are "aiming" to do something groundbreaking are raising at 500 times that.
I think there are more factors than just how groundbreaking their ambitions are that justify different valuations.
Like brands, customer count, contracts, hardware access, headcount, and existing progress.
Thinking openai is worth more than a day1 startup only because they are more ambitious requires all their years of funding, progress, bd, sales, and brand have little value. In my opinion these things matter a lot more than long term ambitions (which always change in response to the market anyway).
I am not talking about OpenAI. I am talking about 5 person startups like SSI which are valued >$1B in day 1 without brand, contracts or hardware access.
