Omicron didn’t kill 800 000 people. There’s also vastly more immunity (whether through vaccines or previous infections). Let’s wait and see but there’s hope it’s a different, milder disease.
But, personally, I would like to avoid getting Omicron, as long term effects are still unclear: does "long Omicron" exist, does it affect vaccinated, and if yes how common and severe is it. There are some recent news about long Covid: it could be micro-clots.

Specifically, reporting long covid symptoms correlates with thinking you had covid, and not as much with actually having had covid.
Of course this doesn’t mean there aren’t some real severe cases out there, but it’s probably not nearly as widespread as it seems.
