It’s being used for what it’s very good at. That means very little applications (although there are some), on a different scale, and certainly nothing that can promise a quick buck for free. Basically, empty promises just farted out.
Most of the real world usage were bogus, either because they did not actually work as advertised, or because they had lots of negative properties for businesses (imagine a system that would try to prevent fraud if done well… nobody wants that). There’s also the issue that a lot of “funky, interesting stuff”, once you filtered out the bad and the ugly, were just… less efficient, less useful versions of what we already used to do.
There are still people clinging to it (and the recent fuckery in the US might revive that… although for all the bad reasons), but the press moved forward to the next thing.
I just hope they won’t move toward the “oh, you use encryption? Let’s see how it protects you from solitary in jail” step too fast.
And no, I’m not sarcastic, I’m worried.
