I didn’t say every one was going to survive omicron. I said the spread was unlikely to be materially higher than its predecessor and likely have a lower negative impact.
A disease that spreads twice as fast is unlikely to infect twice as many people (over the long term). A disease that causes fewer adverse effects, let’s say half as often, needs to, by definition, infect twice as many people over the long run in order to cause the same amount of harm.
As a dumb mental model, if omicron is 30% less dangerous, then omicron needs to infect 42% more people to be as harmful to society. That is very difficult to achieve, especially given our collective immunity achieved so far. I would say there is little chance of this occurring.
