Although in the future, motors will be electric, engineers in their field, for example, mechanics, continue with their specialty developing combustion engines, since they cannot develop an electric motor.
The combustion engine is also still lighter for airplanes. The market is still going on. As long as an invention lasts 20 years, it is a good return for its inventor.
in the 70's, it was thought that the future would be nuclear, and look where we are today. Well, actually today, nuclear plants are picking up.
Never bet everything on the same horse.
