All those things would change the world, and nothing would ever be the same, and would disrupt everything. Except they wouldn't and they didn't.
The scam is that those companies don't want to be seen as mature companies, they need to justify valuations of growth companies, forever. So something must always go into the hype pyre.
By all means, I hope the scam goes on for longer, as it indirectly benefits me too. But I don't have it in my heart to be a hypocrite. I will call a pig a pig.
