I know core devs and hodl, just saying they continuously fail to deliver and that there is doubt that a solution is actually possible. Things get far more complex and the exploits quite interesting
The solution you have come to is a fair one (which is that truly developing a decentralized infrastructure that is reasonably priced to run apps on has too many challenges to succeed, at least the current solution that ethereum is providing).
I have hope that these problems can be surmounted by the ethereum development team. There are lots of challenges, and that is why everyone says we are at the beginning stages.
I think it's worth a shot, and if it succeeds I do believe we'd live in a better society.
Im particularly fond of Hyperledger Fabric, though it is quite antithetical to the crypto narrative.
