What is the waiting period before miners can spend the block reward / coinbase transaction? Why does this protect against chain reorganization? How much energy would it take to reverse the chain back to the genesis block? Should we sustain immutability with proof-of-work or move to proof-of-stake?

These questions are from the Scottish Blockchain Meetup and the July monthly patron session, which took place on June 19th and July 27th 2019, respectively.
