I watched the boring compny video and all he says is that his concept have been known before him.
Yes, duh. But he was the first to make them usable as commercial products by making them 10x cheaper.
Anyone can make a costly prototype of something, but the challenge is making it actually profitable and commercial.
So far the boring company is a money pit. It remains to be seen if they can accomplish anything you suggest they have. For now they're still just a marketing engine.
The ventures that he takes on take normal companies a decade(s) to become commercially viable.
If he doesn't instantly have full products out, he has failed? Why the heck would you expect that??
I'm not saying he's failed. I'm saying he hasn't succeeded yet.
