> what Bitcoin has done to GPUs

I understand your argument, but Bitcoin hasn't been mined on GPUs since 2011/2012. Broaden your argument from Bitcoin to "proof of work schemes" more generally, and from GPUs to "profligate (mis)use of resources", and it will land more effectively.

If you are against cryptocurrencies more broadly, inclusive of proof of stake and other more recent approaches that aim to address the resource consumption issue, then that position didn't come across clearly.
