All I know is that after having a substantial tx get stuck in a submarine swap via acinq's phoenix wallet I'm staying in LN as much as I can from now on, and I'm sure that is in a lot of people's minds.

The ongoing march of exchange adoption of LN is only going to be accelerated by this nonsense. Last time the chain got spam attacked like this, saw the invention of bulk transactions bundling hundreds withdrawals into one. And soon that will be done with taproot schnorr signatures, but nobody else has incentive to max their margin on moving bitcoin around than exchanges.

The chain would never have had the room to accommodate this before. The marginal cost of block space is very low. Miners are deeply leveraged this cycle, and are the clear suspects for who is motivating this spam. Miners count on a certain average volume of transactions and honestly if you hadn't noticed that average block sizes have shrunk in the last few years you aren't looking.

I think Jevon's Paradox is what we are seeing here. Efficiency increases leading to marginal use cases proliferating. The ordinals will stop being printed if they don't hold their value. If we see a ponzinomic bust, everything will be back to like before. NFTs are basically dead in shitcoin world already.
