You mean cryptography? Yeah, thanks to let's encrypt we are now reaching widespread adoption of TLS. You barely see any http websites anymore thanks to that.
You know perfectly well that's not what they meant.
Cryptocurrencies on the other hand don’t seem to be doing all thar well. Their hype-phase is definitely over and not many actually useful use cases remained.
Sure, but I am against the idea that from now on "crypto" has to be forever referenced to some ponzi schemes that provide no actual value.
