Absolute bullshit. Bitcoin does not even use processors for mining, it uses massively specialised hardware that is absolutely useless for anything else. No advances in bitcoin mining will translate to gain in anything else.

It also massively increases emissions and does nothing to decrease them. The difficulty adjustment algorithm of bitcoin will ensure that you always have to keep wasting more resources to mine, and will cancel out any gains you ever make. By design. Bitcoin is explicitly built to waste resources.

by specialized hardware, you mean GPUs? which are extremely useful for graphics, machine learning, and large-scale mathematical calculations? the gains to society that GPUs brought can't be understated. how do you think they run the climate-projection models? [1]

and my argument is about second-order effects. even if bitcoin mining remains inefficient, the technological gains of directly incentivising lower energy usage than your competitors carries over to other markets / enterprises

plus, bitcoin is scheduled to run out. so eventually the mining issue is moot

a second-order prediction is obviously more noisy and holds less weight without any direct evidence, but 'lack of direct evidence' characterizes much of this debate

No, nobody mines bitcoin on GPUs. Surely you would know that if you're here trying to make argument about it?
I was under the impression that standard bitcoin mining leveraged GPUs for the heavy lifting. If that's not the case I'm happy to know what does
There are ASIC chips as far as I know.
It's all the other shitcoins that are mined on GPUs.
That hasn't been the case for most of the decade. I already told you what does: Completely custom-built hardware that can do nothing but bitcoin mining, such as Antminers.

For instance, here is a shipping container that burns 1 megawatt of power in a pure and complete waste of energy and carbon emissions: https://shop.bitmain.com/product/detail?pid=0002021123118285...

alright, in that case you're right, the processors seem wasteful

though interestingly, the specialized processors alkso seem like an example of a second order effect of bitcoin: driving innovation towards more energy efficiency. (though the tradeoff here seems to be wasting materials versus wasting energy)
