Is it actually that bad though Ethan? From a completely non-medical view point the fact that one of the quotes in the article is "There is a lot of speculation, but very few clear answers" seems to suggest that they don't yet know if this is going to be bad or not. Is it possible that it is highly mutated and could be far more transmissible and evade the vaccines, so that far more people get it, but be far less deadly and only give mild symptoms to those that do get it?
The problem with Covid (OK, that's the disease rather than the virus) is that it is still lrealtvely early in its evolution, so the slow slide into middle age being a bitter rather than a danger, is still some way off. This one is still looking for action. Most of the vaccines are directed against the Spike, the sticky out bit, but this new variant appears to be evolving in other areas too, and that could spell trouble for vaccines.
The danger scenario would be if it had a longer incubation period during which it could transmit, and vaccination provided limited protection. Then it can spread widely quietly. If it starts to circulate widely, then that drives further mutation. It is better to speculate a bit wildly (worst case scenario) and over-react than relax and under-react.
