Well, if that dev Bob cited is right, then Lightning is apparently cooked unless a fix is possible.
If so, Phil has a solid argument as you cannot accommodate coffee buying on bitcoin (without Lightning).

Do I care? Not much as my infrequent txs can still be posted, but it (bitcoin) cannot be a medium of exchange for the planet.
Is BitVM any better? I have no clue, maybe it is too new.

Perplexed.
