I think we will have supersonic planes, but they will be electric.

But to get there we first need normal conservative electric planes to make electric planes more normal. Battery have to be getting better for this to happen but I think we will get there, some people overestimate how large battery improvements we need by basically thinking they need to match chat fuel.

If you look at how far the currently in development electric plans can go you can see lots of improvements that can be made to increase that range considerably.

You can also build your air-frame out of batteries. The batteries themselves need to become structural members in the air-frame. Some manufactures are doing that already for cars but for plans it will be even more important.

Things like using a PRANDTL Wing and prop blade would make a large difference for example.

It of course makes sense for startups like Heart Aerospace not to try these things but I think eventually people will. Electric planes will be so operational efficient that there will be huge demand to increase the range.
