It’s a common tactic. Shock an industry with a new product and advertise it as being very affordable. Once you get a solid consumer base with enough organizations that have rebuilt their operations around it, slowly increase the cost and find more ways to produce revenue.

It all depends. Yes, something like that happened with Uber, but computers and consumer electronics have Moore's law working for them, so prices usually go down. (With occasional shortages like we see now with RAM - not for the first time, but it's usually temporary.)

My guess is that AI will be more like consumer electronics than like Uber.
