What if you could CTRL+Z to undo regrettable mistakes in life?

Hello to anyone out there.

Do you ever wish there was a ‘rollback’ feature for life?
For anyone familiar with computers and things like Word processing, you’d be aware of the key command, ‘CTRL+Z’. It’s the UNDO key. It returns the state of your document (or whatever it is you’re working on that supports that feature, to a previous state prior the most-recent change you made.

Well, I wish there were such a button for life. Say something silly that you immediately regret? CTRL+Z is your friend. Make an ill-judged comment to a couple about to get married, or reverse carelessly into an expensive European sportscar? CTRL+Z is there for you.

Putting aside the wishful thinking, what about the philosophical and causal questions around such an object/function? What does it mean to be able to ‘revert’ or ‘rollback’ to a previous state? Does the reverting also mean your brain-state itself is returned to its prior state? Would you not then be likely to make the same mistake once more? Unless you were able to go back in time, as it were and retain some sort of hint that your next action is one that you may want to reconsider? I have no idea.

While I’m freewheeling about non-existent backwards-time-travel by some keyboard trick, let me also say that I continue to hope for a matter replicator like they have in Star Trek : Next Generations and related shows/books. I reckon they would be so much fun. I wonder if the Star Trek replicators share with hypothetical Von Neumann probes the capability of self-replication? That’d be handy — you could easily defuse family arguments over who gets to use the replicator at any one time by instructing the replicator to make several more replicators. And that begs the questoin – would you pay a license fee to a replicator? Would you pay per replication? If you replicate a replicator, do you pay for that second machine and is it just as subject to patent protection as the original replicator? You know what, I’m confusing myself.

Thanks for reading my semi-coherent thoughts.
