Anyone actually counting cards online or is that pointless?

Seems like every other week, someone asks about counting cards in online blackjack. Honestly, I don't really get how folks think that's even workable unless they're talking about the live dealer tables with actual cards, not just RNG games. I keep seeing mixed opinions. Some claim they can track the shoe, but my math brain tells me the constant shuffling and auto-decks just kill any edge you might hope for. Maybe some live tables aren't shuffling after every round, but I have yet to see a place that doesn't mess with the shoe way more than you'd see in a real casino.

Still, I'm curious if anyone here has actually found a consistent way to get a slight advantage, at least enough to make card counting worth the time online. Does anyone have a strategy for this or is it really just a waste trying to count cards unless you’re sitting at a physical table?
