Ampaire (among others) is already making great strides in general aviation. With significant improvements in specific energy (see QuantumScape, HyPoint) and specific power improvements (what we are working on) coming in the next few years, shorter flight routes that were previously not profitable will become profitable (300-500 mile range, > 10s of passengers)- and that’s only the first step. Maintenance cost reduction and of course fuel cost reduction create a very good business case.

To clarify my stance, building an electric version of a dash 8 (for example) is totally possible, but range would be limited and I doubt it would be cost competitive with high speed rail. There may be a niche for planes like that servicing rural airports and chartered flights for the wealthy, but you're never going to fly transatlantic routes.
