Ethereum Classic fell victim to multiple 51% attacks in 2020. The hacker was able to gain control of 51% of the hash power and reorg some blocks and it allowed double spending and all the catastrophes that come with a 51% attack [1][2].

It is safe to say that it won't come anywhere near close to where normal Ethereum is in terms of mainstream adoption.

Children develop object permanence by the age of two. How long does it take for cryptobros to develop GPU permanence ? You closing your eyes doesn't make the problem go away.

But the GPUs already exists, what solution do you imagine that involves the said GPUs to not be used anymore? Even if you sell them to normal consumers, the GPUs will be used, one way or another.

Are you suggesting we should destroy the GPUs that were previously used for Eth mining?

I think the point is that the miners already have the GPUs, they will probably switch their operations to mining other coins/forks instead of just giving up on everything.
