There's also a flip side argument.
Those who say "look at the automobile - people said that never had a chance and they were wrong" are applying 20/20 hindsight by starting with something that's successful now but was once dismissed as a curiosity.
But in the history of automotive travel there are plenty of examples of the opposite: Things that were hailed as "the next big thing" by proponents but that turned out to be disastrous flops.
Steam Cars? Wankel Engines? Cars that could float or fly? Gas turbine engines?
All currently residing in the "what were they thinking?" section of the internet.
I think some form of electric propulsion will eventually become the standard for vehicles, but I'm not convinced it will be 100% electric because of both battery storage limits and charging time issues.
If I was to guess I'd say the "future standard" is going to be something like a fuel-cell hybrid or a hybrid using some other form of power to charge the batteries and create the electric power to move the vehicle.
If battery powered EV's do become a "standard" then I would expect it would radically change the way we travel. A multi day trip would not be done the way we do it now where we load up the SUV, fill it with gas and then spend 2 days driving to Grandma's house, stopping only for gas, meals, lodging or to take a photo next to the World's Largest Ball of Twine. Instead, you'd have to plan your trip to drive to, say, 75% of the battery limit (maybe 200 - 300 miles depending on the size of the vehicle) and then plan to stay several hours while parked at the charging station.
Another possibility might be charging stations at 100 mile intervals with cafe's, playgrounds, WiFi, etc, and the way to take the trip is to stop every 100 miles or so, spend an hour or two at the charging station and move on to the next one. I'm not sure that model would work in the sparsely populated West but you never know -we humans are endlessly adaptive. ;)
