Right well, thats why there is a new hashing algorithm. And they want other energy heavy cryptocurrencies to switch to it. Basically there is a whole row going on in the far far corners of crypto land, where some Cambridge and Columbia university alumni have made a new hashing algorithm (HeavyHash) that is heavy on linear operations specifically so that it would theoretically have an advantage on light based computers and be a sustainability solution [for now]. They stood up an example project back in May and forgot about it ("optical bitcoin", oBTC), but people kept mining it. Just on GPUs and FPGAs, as the low power better processors don't exist yet so there isn't really anything different at the moment. Because these are students with no funding, the management is very weak. There is at least one fork of that project that has better management ("photonic bitcoin", pBTC). But they are waiting for OPUs to exist at all, as there are a variety of vaporware companies out there with massive funding. HeavyHash itself is being used in more and more other newly launched cryptocurrencies. Hoping for OPUs to become available to actually make their networks different than others. They all so far only aspire to be examples for other major energy consuming cryptocurrencies we've heard of to switch to. The university students had submitted a proposal (BIP) to Bitcoin-core, and that slow moving network typically needs real world examples and fear of missing out for consensus to shift.
