You can go 100 years into the future, save humanity, but not come back. Do you?

Just let me set up an interest bearing account at a bank they can confirm will still be there in 100 years.

Yes, I’m curious to see the world of 2114.

Provided they ensured my books and other things are kept safe in storage for the period, sure.

If I can’t get back, why could they? Are they planning to kill me by taking every last drop? Have they instituted a sacrifice and can’t trick anybody in 2114 to fall for the test? They now have to recruit antiques to slaughter?

I’m old and this life is boring - hell, I’d go just to see how time travel works.
