No way the chip costs $19,000. I agree with you: Tesla priced it high so nobody would buy it, though a rival company could pay $19,000 in an eyeblink if they wanted to try to reverse-engineer it. They'd probably buy a few dozen. Maybe already have.
The Intel Core i5-8400 @ 2.80GHz 58.47 costs $200. The new Tesla chip probably costs 1/100 of the "list" price. Less to Tesla since they will buy it in bulk.
I'd say that yours is the majority view here, not an unpopular one. The technology is new and therefore immature and so there are a gazillion improvements and corrections to be made, and we all have our opinions and if we're on a web forum we're probably all pretty vocal about them. But yes, by all means, this is a "wow!" time to be alive and watch all the new stuff and play with it. Whether or not we agree with the OP in this particular thread.
