Trucks move people and items. Bitcoin allows us to buy porn, pot and run scams on a mostly centralized network.
Can you explain how it is centralized? Because… it isn’t.
there's only one blockchain

Imposing global technological bans so willy-nilly seems like a nice idea only on the surface. Things like machine drying your clothes at home in the US (uncommon in Europe so seems frivolous) uses as much if not more energy.

Would you support Visa and Amex if their next generation networks required you to burn x minutes of natural gas or x pounds of coal to complete a transaction? Why is this an acceptable architecture for Blockchain? It is a race to the bottom.
That’s absurd comparison. No energy user (be it miners or the visa network) requires unclean power. Electricity is fungible.
We all want power to be cleanly generated. This demand side bullying needs to stop. Give us clean energy!

> And crypto needs to be banned because it's all a gigantic scam that has a gigantic environmental cost attached to it. Is it worse than, let's say, Christmas in this regard?
Yes
How so? Christmas lights, plastic trash, food waste and transportation combined?

Are you suggesting that you could use Raytracing at all in modern games on a low end card like the RX 6500 XT? If you would use it you would lose the marginal performance increase of the updated architecture. Also content creation is a big point for younger generation if it is livestreaming, recording clips or general gameplay. This will both not be doable with this card if you don't have a good cpu. There is no disc…
> Are you suggesting that you could use Raytracing at all in modern games on a low end card like the RX 6500 XT? Yes? Minecraft Raytracing and Quake Raytracing are rather low-specs and probably would run on an RX 6500 XT. You might have to drop down to 720p but it probably would run.
Minecraft release 18 November 2011.
Quake release June 22, 1996.
They may have frankensteined the engines to support ray tracing but these are not modern games at all.

A single miner uses 1,300W (Antminer S9) and runs 24/7. That is 218,400Wh for a week. A gaming computer at ~400W, left on 24/7, is 67,200Wh. That assumes you are playing 24/7 - your idle wattage in sleep is If you run your dryer every night of the week for an hour, you are using about 38,400Wh. You can game 24/7 and dry your clothes every night of the week and STILL use less power than a modern, efficient single mine…
Yes, but the real question always is: Who will make a decision as to what is considered frivolous. Not to search very far, I consider trucks in US for non-contractor use to be frivolous, but I don't go around telling people those need to be banned.
> I consider trucks in US for non-contractor use to be frivolous, but I don't go around telling people those need to be banned.
What does you not liking trucks have to do with the issue of putting limitations on mining crypto?
Just because you don't care about this random issue doesn't invalidate serious concerns other people have.
Also, this is a pretty bad faith argument to say 'who can make these decisions'. We make rules in society all the time. If enough people can be convinced for a particular regulation and the laws of the society allow it, then it'll be implemented.

#136AMD consumer cards are unusable for GPGPU. Utter garbage. It’s not just mining. I would not have bought them if it weren’t for their open source driver. I hope Intel Arc fares better.
Isn't it because of CUDA?
Yes and no. AMD uses different architectures for their consumer grade hardware and their HPC stuff as well (i.e. RDNA vs. CDNA).
CUDA support (or rather lack thereof, which isn't AMD's fault) plays a major role w.r.t. software support, but AMD's compute architecture isn't DL-focused either.
The MI250X compute part for example has a FP16 to FP32 ratio of 8:1 and a FP32 to FP64 ratio of 1:1; in other words it's an absolute beast at GPGPU compute.
The 6900XT on the other hand has a FP16 to FP32 ratio of just 2:1 and a FP32 to FP64 ratio of 1:16 (i.e. it's severely restricted at high precision workloads and OK at half-precision).
Comparing this to the specs of NVIDIA cards, they're still vastly superior on paper. The consumer versions of Ampere only get 1:1 (FP16:FP32) and 1:64(!!! FP32:FP64) respectively. But then again, NVIDIA cards feature dedicated "tensor cores", which have no equivalent on AMD consumer grade hardware.
The main selling point for NVIDIA, however, is software support and mindshare. They started to buy themselves into academia in the late 2000s by sponsoring labs and providing a vast ecosystem of software libraries for deep learning and GPGPU support in general. This not only helped kickstarting the deep learning revolution but also tied their hardware and brand name to GPGPU, which basically became synonymous with CUDA at that point.

I think OP point still stands. This is comparable in term of "waste".

Ah yes, I’ll never forget when I purchased my house and the armored truck delivered my money to the buyer. /s Most transactions don’t need a decentralized trust-less value transfer. But bitcoin is not only attempting to displace the small sliver of transactions that DO need trustless/decentralized
I put a 20% downpayment on my house and it involved a wire transfer that was scheduled for days in the future that required my physical presence at a centralized authority (bank). With Bitcoin, that process takes less than an hour, with very little "fee", and doesn't involve any of the "trust", which was represented in my example by time delays, scheduling, and traveling.
Oddly enough making buying a house faster is not really a priority for me. I appreciated that mechanisms of trust kicked in for that transaction - my bank wouldn’t release mortgage money to anyone but a lawyer or notary, and my notary would not have released money to the seller unless they actually owned the place and transferred ownership to me.
Making that trustless means I am open to scam sellers, and have to trust the seller (who stands to gain if they can trick me) instead of now where i trust the bank and the conveyancers instead.

Lets say Coinbase and Paypal (both BTC processors) stop supporting your website. Do you think that you'll get as many BTC transactions if this happens?
I don’t think you understand how cryptocurrencies work. There ain’t much Coinbase and PayPal can do to stop someone sending coins to my address. I don’t have a website, nor do I care what Coinbase or PayPal do or say.

#140World really needs a ban on PoW cryptocurrencies. I guess on one side lot of people is not caring about it as long as they make some money of it, and in the other side maybe other people in power, is not caring as that would make a perfect excuse to ban any kind of cryptocurrency. I guess too we all will care as soon as the devastation caused by the climate change becomes a massive life threatening issue.

Fine, yes. Ban both.
