Has it been replicated yet?
This is the most important question, imho. Especially when economics are involved.
If it is true, processing power and gpu power will increase dramatically, but not before some heavy duty geopolitical drama plays itself out.
This is happening amid the backdrop of China seeking to "reunite Taiwan with the mainland", TSMC seemingly getting cold feet regarding their fabrication plants in the mainland USA, and a US congressman saying publically that we would blow up TSMC in a confrontation with China in Taiwan if need be (really, REALLY stupid move).
This makes for a weirdly charged situation in regards to the worlds existing fabrication plants. Granted, this superconductor probably has a different fabrication process, but it will likely need to live alongside semiconductors for a long time, and if it is indeed as efficacious as the study says we will need to change a lot of core architecture to utilize it properly.
So, what we have is a need for a new process that will likely require a reorganization of existing electronics methodologies (which takes time), alongside a geopolitical powder keg (which can modify the time that said changes need to take)
Once it is active, it will probably go through the beginning phases of a technological lifecycle, which could either be on the slower end or on the faster end. Likely it would be a gradual growth of the technology, climaxing in a seemingly lightning speed shift in existing hardware (like the CRT to LCD transition)
For gaming, the human element is a limiting factor. The NEX GEN GRAFIX that we see nowadays takes exponentially larger teams than we required before. More computational power means more can be done, but we still need humans to create everything.
In the end, though, certain stonks are skyrocketing right now and the hype is growing rapidly, so Torrent of Pork's succinct question is all the more important.
