Earlier quoted context omitted.
Delta managed to thread the needle and grow both more deadly and have higher transmission. I'm sure some variant in the future will improve both deadliness and transmission. But there is a low chance that this variant (or any particular variant in general) will accomplish this feat.
Is Delta more deadly? I thought that was not really believed to be the case any more, just that it is much more transmissible. I could totally be wrong though; it's hard to find reliable info.
> However, the highest risks were from the Delta variant. In the Delta cases, there was a 108% increase in the risk of hospitalization, a 235% increased risk of ICU admission, and a 133% higher risk of death, compared with the original variant.
Its very rare, but it does happen. Delta is proof of it. But chances are, we won't roll "snake eyes" again on the most recent mutation.
Mutations are random: they can improve, or diminish the virus. Especially on something as important as the spike protein: that is literally the site that binds with our cells. Omicron could be better... or worse... at binding. There's all sorts of questions that are up in the air.
From a policy / scientist point of view, it makes sense to "hope for the best, prepare for the worst". That is: we should react as if its a worst-case scenario mutation, but we need to keep hope until the proof actually comes in.

A lot of information will come in the next couple of weeks: I'm sure supercomputers are simulating how this molecule now interacts with our bodies (but those simulations take days or weeks to finish accurately). There are surely trials and science to be done here.
Omnicron is a wakeup-call to the scientific community. But I'm not sure its worthy of being discussed in public yet. There's just not enough information here.
