You know, people used to be able to put their cars on trains or boats for long trips... perhaps we could bring back that old tradition for holiday travel. It would be a lot more energy efficient as well.

Heck, my daughter takes longer than that just to use the restroom...

That's a silly argument. Wouldn't most gas station simply convert to electric charging stations as gasoline sales wane?

I'm pretty sure that problem was solved a long time ago by the fancy contraption called a "bush"...

You forgot: road maintenance currently financed by a tax on gasoline and diesel, not electricity...

On long trips, horses can eat the grass growing along the side of the road... where the hell am I going to find petroleum products on a long trip? (The supply generally tends to expand to meet the demand. If enough people are willing to pay to quick-charge their electrics away from home, some entrepreneur will build the charging stations. Most will simply take over some of the space in existing gas stations.

Right... cause the neighbors cat, small children, and various other small animals will NEVER be out on your lawn..

No problem! You can always buy a gasoline-powered generator and charge those batteries right up!

"How many miles per brain are you gettin'?"

The tipping point will come when a usable battery pack costs less than $30,000 (more than a low-end entire car). Sure, the Model S is nice, but at $70,000 to $120,000, it's beyond most people's means. People can keep claiming they are going to come out with and affordable electric with great range "any day real soon now", but until I drive out of a dealership in an electric car with the 200 mile range of a Model S for less than the cost of Honda Civic, I'm going to keep insisting they are full of shit. (Yeah, the Bolt sounds cool, but again, I'll believe it when I can actually purchase it.)

It doesn't matter how much better any new CPU design is. Unless you've got a billion dollars a year to invest in making it better, you're simply not going to keep up with Intel, and it will soon be obsolete. And unless you're selling hundreds of millions of copies of that CPU, you likely don't have a billion dollars a year to invent in R & D. Unfortunately, CPU chips are a textbook case of a "natural monopoly" i.e. "A natural monopoly is a monopoly in an industry in which it is most efficient (involving the lowest long-run average cost) for production to be permanently concentrated in a single firm rather than contested competitively." Sure, Sparc was cool when it first came out. Now, it's just a curious anachronism.

if your enemy doesn't like you on their networks, they can always disconnect or turn off their machines.

the only way to win is not to play.

dammit man, haven't you ever seen a disaster movie?!

look, none of this is a problem as long as nobody asks about the worst case scenarios.

the real question is when will we advance this technology far enough to not just be an assistive device for surgeons to actually being the surgeons?
