there likely will be a day where there is nobody left who knows how to use dominant blockchains and rely on a few company controlled platforms to do everything for them, so there is nobody left to communicate with when using the public utilities in the most raw form.

For now, that's not the case and education is expanding. Not as fast as the uneducated users of blockchains, but some of them dive deeper too.

Even now this is the case. It's a bit more spread because many people jump on the bandwagon and try to maximize their scams^W profits.

But then you get news like "Peter Molyneux releasing next game on Gala Games platform", and this is exactly what I'm talking about.

It doesn't matter how many users and devs you "educate". If Platform X doesn't recognize Platform Y's metadata, no amount of blockchain will help you.
