I think most people see where the puck is going, and even where it is right now is very impressive. It's not hard to see that it will be likely less than 5 years before it will be able to do what you did on day 2, and much more, at a tiny fraction of the cost, with no downtime, no attitude problems, sick days, etc. The things you mentioned (taking on board feedback, testing across devices, iterating on solutions) doesn't seem very far away at all.
The rate of increase in capabilities is also unpredictable, which is what is amazing & terrifying.
