In order to make it in the crypto market this is the way they have to behave, because the measure of success is the coin price, which is directly tied to the number of people buying into their coin (the vast majority know nothing of the underlying technical details and don't care). It's a race to the bottom and a real problem with the industry, reminiscent of the dot-com bubble, but I think far more pervasive in crypto. This is also why crypto will keep experiencing popping bubbles until it finds enough use cases with actual advantageous compared to existing solutions.
I'm saying, if you dig beyond the hype machine, you'll find plenty of hard core tech and tech adopters that you found in previous platforms, like PC and internet.
OP apparently cares about the underlying technical details. I'm saying if he/she looks deeper, they'll find what they're looking for.
No, that's not true. It's just those types are the loudest. So that'd be your impression when you haven't spent time looking into it.
But it sounds like you've at least looked at Vitalik's writings. The Eth core has plenty of hard core tech in various corners of crypto. It's just that they're organized by project, and not all in one place.
