The “bitcoin wastes electricity” punchline is definitely a major embellishment embellishment *at best* but you have to admit it’s not a good look for mining facilities to accept local power prices. That’s a negative externality and needs to be acknowledged.
As for this video… what is the point this guy is trying to make? Of course computers don’t emit CO2, it’s the fossil fuel plants that (largely speaking) power them. Responses like this video make the industry seem silly imo.
