The future of Bitcoin mining must be either oblivion or reversible computing. I shudder to think of the electricity wasted otherwise.
Quantum computing is many, many years off.
Well if we get to the point where enough electricity is used to equate to 1 nuclear powerplant running at full capacity
We may need a more efficient coin.
(Unless we replace a lot of fiat currency printing and associated costs, with electronic transactions over the block-chain then more math is required to see which is more efficient over time)
On Quantum just said in the future no real timeline for it just someday the final chapter spoiler
