i though similar for years now, maybe we should give some classifications, like your covid 19 predictions, your life on mars, and so on...
covid - 19
no effective vaccinations will be found, chances of you dying from it will increase, by the factor how often you will get it (reverse tolerance).
life on mars
yes will be proven in my lifetime, but some people will claim, we brought it there, via space travel.
return to carbon low emission transport and energy
yes, move goods on water ways/canals, instead of roads.
