Self driving cars: Yes, but only if they really work - now is the perfect time to sell them if they did; for those of us who normally use public transport but don't currently like the thought of sitting in a petri dish for 2 hours. Utility scale battery storage: Yes but it needs tech improvements to store LOTS of energy; the flow batteries might do it if the hype is true - but currently the UK wholesale electricity price is £-28/MWh due to a wind/solar glut and a quiet weekend, so if anyone wants to get paid to store that energy the opportunity is there.

As for C++ safety; I find modern C++ hard to read - are they going to be able to do safety but end up with something that's actually harder to use/read than Rust?
