I think electric will catch on and become very cheap.
I say that in the vein of a guy in the mid 19th century who sees an oil well and says, “I think we can power carriages with that stuff instead of horses some day.”
As with that 19th century man, “some day” is a ways off though...
Well, compare a century of development of electric cars (the damned things have been around since the turn of the previous century) with a century of internal combustion engine development.
