Right, I put it that way because they are real, hard problems.
Still, we've come a long way from impossible if we are merely looking at a hard problem.

I also think there’s a chance that costs of renewable construction and replacement go up as fossil fuels get more expensive. Right now most heavy industry and mining relies on fossil power due to portability, energy density, and preexisting equipment. It’s not necessarily going to be a smooth transition, especially in politically dysfunctional countries. The bottleneck period will be difficult.
