I don't know what physics you refer to but nothing in the universe as I understand it "lacks entropy". Intelligence in the human, in the non-human animal, or in the AI, is physically equivalent as we currently understand physics at least. That being said my point is that mining does not actually require human emotions or any high order thinking. Mining by way of Proof of Work is a 'set it and forget it' situation.
On top of it being 'set it and forget it', it also promotes automation by design. Block reward halving happen every 4 years and this promotes increasing efficiency indefinitely. The logical way efficiency is increased is by cost reduction of the business operations. Eventually the inefficiency will be the human beings and the botnets will be the most efficient mining businesses until eventually a fully autonomous botnet is released.
Tell me why this will not happen? It is happening already. People have been finding hidden miners on websites all over the place. It is starting to become ubiquitous and even Intel is mentioning releasing a chip with a miner built in. Once the ASIC is built into the Intel CPUs, and the AI chipset built into the GPU, well how long before what I predict to happen becomes reality?
Assuming all computers will not have ASICs in 5-10 years is ridiculous. They all very well could have ASICs if it is profitable for Intel. I doubt it will even take 5-10 years, we might begin seeing these chips next year.
The one point you used to refute my hypothesis is that the current chipset is 14nm? But you do realize due to physics we will reach a maximum efficiency for chips pretty soon. When this happens the only way to scale is more chips not more efficient chips.
