What would happen if the Earth's tilt would shift to 45 deg
suddenly or in a short period of time? Would we survive?

Humans are as adaptable as rats and cockroaches. But I imagine
a few billion would die, and all our civilization and social
structures would collapse.

(It is likely that our Moon is what has kept the tilt of the
Earth's axis so stable. Mars, for instance, has seen much
wider swings.)

Well, 500 years ago, earth's population was around 500 million,
now 7 billion! 200 years ago , industrialization caused the
exponential population growth! Going back to 1/2 billion would
be a normal thing, I think!

I'm all for a reduction of the human population back down to a
billion or less.

You volunteering to go first?

I guess you're unfamiliar with the meaning of "attrition".
