Oh, just the death of the planet through waste heat buildup. That's all. Just a small matter of code should fix that.
Are you telling me that there is not already physical evidence for such? I assure you there is plenty of evidence for physical space being assimilated by the incentive structures related to bitcoin and its progency.
Taken across time to a civilization that grows into further complexity, there exists a limit into how much space can be used to secure the network, and most likely even incentivizes maximizing capture of space for computational security therefore it accelerates our civilization towards creating a black hole. I couldn't come up with a better way to fast-track our way towards a cosmic environmental disaster. It's a pretty bad incentive structure long-term.
If only we could get rid of artificial scarcity.
Even in a world where computation doesn’t become more efficient it still takes up the total space available eventually due to the incentives of protecting against network failure.
I will NOT grant you this. Please, give me actual technical details on WHY it requires ever increasing compute. You've said network security, what about it requires ever increasing compute.
You can read the paper and understand the principles it is based on, which is rooted on balancing computational asymmetry amongst other concerns across a network of computers. On the most simple level, if you are aware of hashcash and sybil resistance you should be able to figure it out.
If you're still confused: then answer yourself the question why does the bitcoin algorithm adjust to computational power?
Just fucking say it, what's with the running around?
Are you unable to explain it?
But maybe you have links to others who are able to explain it, not the Bitcoin paper which obviously does not lead one to think network security will subsume all available matter for compute.
