“I would not go so far as to say there will never be viable electrics”
There are....in their niche. I’m not trying to be cute, but a golf cart is an example. Never very far from a charging station, a defined, understood transport requirement that doesn’t vary much, and never so far away that you can’t walk back to where you started.
Mass market electric cars will fail because they do not meet the “golf cart” test - so there will be a risk of exceeding the operational capabilities at all times.
