The only way out of this was all the way in the beginning when we had a chance of stopping it through lockdowns and vaccination but that's no longer an option. The virus is spreading faster than our vaccine manufacturing and uptake capabilities. This virus is here to stay, it has become endemic.
It's also not surprising. This is exactly what ecological theory would predict for a monoculture. See what's happening to bananas with tropical race 4 infections.
it is possible for delta and omicron [and or others] to recombine genetic features, how probable is the million dollar question at the time

What comparison are you trying to make...? Are we similar to bananas?
