Physics might seem easy to you now but flying was an impossible dream for most of history.

The other problems may become more amenable - one just can't know what will happen. Amazing things like CRISPR - an incredible tool that lets us edit genes - appear suddenly and change everything.

Sequencing a Genome once seemed a massive task and now it's no big deal - so perhaps some of these problems will end up like that.

We can also re-engineer ourselves and that might help a lot.
