One thing interesting to me is solid state batteries would be a boon battery powered aircraft. Current 150 to 200 miles range. If you double capacity then 300 to 400 miles range becomes possible.

My rule of thumb with range is if you can go from San Francisco to Tahoe that's a notable milestone.

Also with AI it feels like we have 8 billion people in the world who are intellectually under utilized and often under fed.
