I would go forward in time to see how the world is in 10 to 20 years - look at the effect of vaccination against Covid-19 (and any anti-viral treatments they found effective) and come back and tell you all.
How do you know there's anything or anyone left in 10-20 years time.....or is NMRN already a time traveller? Dr Who?
That's why I said I will go and see. Could be like 'Planet of the Apes' - but, hey, that would suit me and I would not come back. But, to be honest, I have been forward in time and can tell you that you have great fortune ahead of you - and you share it with me.
I think I meant 'backward' in time! Anyway, time may be a loop and so both could be correct. Or it may not exist and so both are incorrect.
