Gas isn't going away anytime soon, hybrids will be a thing for a very long time, as will full gas powered cars, but electric will replace more and more gas vehicles and electric will move heavily into the luxury and performance segment, as its been.
eg Who wouldn't want a large luxury AWD Cadillac with 1,000 lb⋅ft of torque at 1rpm?
Also look for electric, especially hybrid, to start creeping its way into the diesel/shipping market. A semitruck with a diesel and electric motor(s) just makes sense. Lower emissions and better fuel economy.
