The mining space changes so rapidly that it’s hard to predict what the next innovation will be. There is a clear demand to make a device that is both flexible, adaptable and faster than common GPUs. Even small percentage advantages might be worth it for those entities at scale. It’s a toss up whether or not those entities will choose to sell to the public. My thought is that they won’t, finding it more profitable to keep innovations secret and competing with other well funded entities doing the exact same thing. Public mining days might be numbered, which is a sad proposition.
That said, I think it will probably take 5-10 more years for the mining industry to fully mature to a state of predictability. At that time we will be in an entirely different class of hardware focused on extremely low power usage and highly efficient cooling designs. This will most likely shift to two-phase immersion cooling with novec-like fluids (these are really cool btw). As non-mining data centers move to these more efficient technologies, to get higher density per sf, the prices will decrease dramatically for other industries like the crypto mining space. Advancements happening are both fascinating, exciting and also at times worrisome considering our goals of a fairer coin distribution alongside a highly decentralized and secure protocol.
