That's one of the more convincing arguments I've seen.

I still hold though that Bitcoin was an early prototype and its value will sooner or later approach zero.

I do however think that blockchains and cryptocurrencies are a good idea and here to stay.

To build on your example:

Linux is here to stay but a number of the old companies, distros and packages are either gone or on life support and newer companies, distros and packages are making our wishes reality.

I can't help but agree with this. People can only mine so many coins. Users will prefer blockchains which have lower fees and transaction times, so miners will give priority to those coins. At some point the selling point of Bitcoin will become less and less true. I have rewatched several promotional videos for Bitcoin pre-2015, and most of their claims are false as of late 2017.
