Yeah the first web boom then bust... everyone thought it was over with no way to make money.

Personal computers, mobile phones, genome sequencing, MOOCs, email, the telegraph, phones, the railway.

There are examples where it was just straight up overestimated as well of course, like AirPower in warfare but air travel was definitely under estimated too. A plane is a flying bus and people travel across a continent for a weekend trip.

I agree. Initial boom, then loss of faith, but in the long run probably eventually will all be some form of crypto.

Not sure why this is downvoted? Is there any clear reason to think blockchain is exempt from this?

or more importantly -- no one has the battery building abilty that Tesla do.

Waymo can do inner city driving better than Tesla and GM can do highway driving better than Tesla.

I love the competition amongst the different platforms, as a consumer it's a win for us. I could care less on which brand does it better.
