And we're also practically flying towards cheap renewable energy so PoW in general becomes less of an issue every day.
Now you've totally ruined your credibility. I suggest you get an education in Economics before you try to challenge me:
http://www.truthcoin.info/blog/pow-cheapest/The security of PoW is the amount spent on energy. If energy gets cheaper, then the hashrate will increase so that the total amount spent remains the same.
I think the security of PoW is more about the total cost of the network - heavily discounted by centralization of the miners - and not just energy.
Universally cheap electricity would definitely make mining more accessible and less of a problem in general (eg. environmental concerns, miner centralization) and definitely not make it any less secure.
I mean miner centralization is party there because not everyone has access to cheap electricity and it's not like the biggest farms doesn't already work with dirt cheap electricity anyway, because they do.
With cheap renewable electricity the importance of geological location or having to have ties to obtain cheap electricity would be a thing of the past and almost all the investments would go into ASICs
potentially allowing more people to start mining.
More miners = less centralization and renewable electricity = less environmental concerns so I stand by what I said.
Not sure why the hostility and quick judgement though.
