You are not considering the inertia associated with network effects. The reason the internet has never upgraded from IPV4 to IPV6 is because too much hardware and software is dependent on IPV4. Bitcoin is like IPV4. It's just a base level protocol on which innovation can be layered.
The internet is in the process of upgrading from IPV4 to IPV6, and will continue. There's not much choice, given the limit on the IPV4 address space.
Bitcoin isn't like IPV4, because IPV4 wasn't the first. Bitcoin is like NCP (if my quick dip into wikipedia came up with the right acronym). NCP lasted about twelve years, it looks like. It was mostly used by geeks. Mainstream acceptance wasn't achieved until NCP was phased out in favor of TCP/IP.
You're missing the point entirely.
The internet did not go away when it upgraded to IPV4 nor when upgrading to IPV6.
Sorry, but you are the one who does not understand it.
In his analogy it is not "Bitcoin == Internet" but "Cryptocurrencies == Internet" and Bitcoin would just be one of the groundbreaking, early but eventually replaced layers. And the internet did propbably not "go away", but it has become something different and it works without any of the "original" hard- and software.
To believe that nothing will ever be good enough to replace BTC is outright stupid. You cannot just merge all new and/or useful tech into an existing "product" forever and "block" all competition by doing so.
Back on topic:
The cult is selling "Immortals" for USD 6.00 :

Honestly, how can someone buy something with such a stupid name, is immortal better than "never obsolete"? What's the next step, "almighty" or "divine" maybe?
