What are you most excited about account abstraction?

* gasless tx & sponsored tx
* sessions - give temporary authority to systems to make tx on your behalf
* batched tx - approve & make tx in just one signature
* social recovery - recover your wallet without having to memorize your seed phrases

i want these:
tx authority either via a specific EOA (my ledger) or 2/2 (one is my browser wallet, one is an entity that signs when i tap my yubikey). tired of using hardware for day2day stuff. I want ultimate self-custody but don't want to use my hardware on daily basis.
