Can you write a future article discussing the role of hard forks wrt 51% attack threat via a natural monopoly (miner is honest but defeats all competition)?

Perhaps you’ve already done it, but also some more details on how changes in block size will progress in terms of bitcoin-miner power structure? If no one controls bitcoin thanks to the strength of the original protocol, how can you currently be so sure block sizes will achieve 1 TB per block?

Will difficulty adjustment ever move linearly down (like its moved linearly up since bitcoin’s inception) due to long-term rising costs of transactional-labor of the miners (as transactional load goes up, less room for arbitrary puzzles of increasing difficulty?). Or do you consider them independent?
