Hybrid!
Most of what I've seen talks about actual use of this is in a hybrid configuration. Use batteries to power the motors for takeoff, then switch to conventional turbofans for cruise at which time they can also recharge the batteries.
Or use both electric motors and turbofans for takeoff. That allows the turbofans to be optimized for cruise without the high-power requirements that takeoffs currently require. The idea being improved fuel burn and less noise.
And probably coming to commuter planes a long time before you see an electric A-380.
