0 unread replies on the sites I use regularly (HN, reddit, twitter, messenger) and 0 unread emails in the Primary tab on gmail.

I used to be inbox-zero in all gmail tabs a couple of years ago and I will be yet again some day. The main limitation I'm running into is that a lot of useless emails ("We're making some changes to our PayPal legal agreements") have unpredictable subject lines and are sent from the same address that sends useful emails. I already have hundreds of gmail filters that auto-archive useless emails with predictable addresses or subject lines ("Your statement is ready") that I can't unsubscribe from without closing the account. LLMs should solve this problem some day.
