@Yaminosenshi My point was more that there's a pattern among American tech companies and entrepreneurs.
On numerous occasions, they have promised that they are going to imminently introduce a futuristic world-changing technology, at scale, in the near future.
Then they failed to do so.
And they know, at the time they make the promise, that it's unrealistic.
The hype helps them attract investors and gain good publicity.
Now, some of those technologies will emerge in the future. But they are not going to be released at scale in the near-term by the people who promised them.
