Interesting video - I wouldn't say the interviewer was very professional, but the interviewee is a typical NFT snake oil salesman type. His argument is "these things could potentially have value if people decide they will" which is true as far as it goes. But he provides no reason as to why they will or should. He just tries to hype people up on the idea that they might get big, so buy now! And I will grant you, something out of this will get big. But most of it won't.
Miners on oil rigs - not a bad thing, but I would imagine a very niche and minor portion of overall mining.
Energy Provider Control on East Coast - one individual, using the type of demand side management that is common practice for large utility customers. I would say this behavior makes this person better than many miners, but still fundamentally bad.
The bottom line is that you are using huge amounts of energy for something that is unnecessary. You can argue the value of crypto in general and I'm willing to listen, but the proof of work method is certainly unnecessary.
GaryV can definitely pump NFTs, but he has also said that most NFTs will go to near zero. Some of them will become brands. Some will become gaming companies. Some metaverse brands. Some of them art.
I've been involved in mining since $50 BTC. I don't think 75% type numbers are doing something like the oil rigs. But I also think the numbers we get told are way off. Power is the biggest cost input. Even people that don't care about the environment are driven to some pretty creative ways to get it. I was at one pitch meeting where the miners were going to setup in a remote, green energy, very cold area. They would use the exhaust heat to warm green houses and grow fresh vegetables; which they were going to give away to the community.
Unnecessary is literally just your opinion. I would call Christmas lights totally unnecessary. I'd call gaming rigs and consoles unnecessary. I'd pretend that air conditioning is completely unnecessary because really it is but I'm not going to stop using mine.
But I've really tried to stop arguing energy use with people. A bunch of NFT blockchains are already on proof of stake. ETH 2 is proof of stake. The ones that stay on proof of work can try to justify it.
