The people who survive this century are mostly going to be wise and experienced people

 Or people who are taken care of by wise and experienced people.

All the rest might not make it. Why?

Because here's the thing. You can get coronavirus (any variant) multiple times. We already have records of people around the world that have had it at least 3 times already. So, there might not be any limitations as to how many times you might get it.

Therefore, if the first time you get it doesn't kill you then the 4th or 6th or 10th time you get it might.

Therefore Dr. Sangay Gupta's statement: "Get Vaccinated or Get Covid" begins to ring true.

And if you get Covid enough times it is likely to kill you one of those times no matter what age you might be young or old. So, it really doesn't matter how young or strong or immortal you might feel right now eventually it will get you if you aren't vaccinated even if it is in 2030 or 2040.
