Comment Re:It's about landmass (Score 1) 397

If you reread what I wrote, I said that in general, the most costly maintenance that needs to be done on cars doesn't tend to happen any sooner than the extended warranty would *otherwise* offer. I did not suggest that everyone would necessarily get an exteded warranty. I do, but that's beside the point. My own experience is that the costs of doing so are *MORE* than compensated for by even a single unexpected incident that would otherwise be covered, and are in fact only modestly above what you would have otherwise paid for the kinds of regular maintenance it covers in that period anyways. bviously they are making a profit on it, but I don't object to other people making money, nor do I object to paying a little more for a convenience factor. I *do* object to paying more money for something that is less convenient, however, and the cost of maintenance over the first 5 years or so works out to perhaps a quarter of the price difference between an EV and a comparable sized vehicle, where gasoline is perhaps double that. Just around the time that the different in up-front cost for an EV might otherwise start to pay for itself in terms of savings, you have to replace the battery, which chews up another several years worth of maintenance and gasoline. Sure, in the long run an EV will save you money.... but the amount of time that you have to wait for it to do that is longer than the time that most people even own a car, unless they drive old beater cars that are so reliable that they'd be nuts to consider a trade-in.

And frankly only an idiot buys a new car.

Bad form... that's called poisoning the well, and is a type of ad-hominem argument that is equivalent to a logical fallacy.

I buy new cars because my experience has been that they have fewer maintenance issues and unexpected surprises than used vehicles. This makes them easier to budget for. I don't buy a car because I expect to get my money back, I buy a car to reliably and economically get me from place to place. Generally, I will try and drive a car until the cost of maintenance starts to climb to unacceptable levels. This invariably happens much sooner with used cars than with new. And somehow, my trying to be prudent with the money that I have at the moment makes me an idiot... Not sure how that works, but if you want to believe that, I'm not gonna stop you.

I saw the typo instantly after I hit submit, but I was hoping it would be clear. Apparently not.

What I meant was:

Do you seriously think the gigafactory is going to be making anything for anything but luxury-priced cars?

It's Tesla's gigafactory.... And Tesla is not cheap. Even their so-called economy model costs more than 3 times as much as a similarly-sized gasoline car. Tesla isn't about to lower their price because they are already associated with a luxury brand, and people who can afford them are buying them, so Tesla has no incentive to drop their price.

Comment Re: "quantum" computing (Score 1) 43

entanglement establishes an instantaneous signalling is grossly wrong

look at the tachyonic anti-telephone: https://en.wikipedia.org/wiki/...

using non-local quantum entaglement to instantaneously transmit information indeed would be faster-than-light

humans have not achieved non-local entanglement, nor have they used it for computing, and unless you redefine "quantum" then it's not possible for these to be "quantum computers"

yes, you're right that we could only verify the signal transmission at light speed, but if it is instantaneous then it's instantaneous...if the phenomenon happens and we verify it then the ability is confirmed...time is more than just what any one observer sees and we can determine if something was instantaneous vs faster-than-light...why couldn't we?

I'm just a telecommunications scientist so this is definitely out of my expertise in some ways, but I think I know enough to understand that true non-locality has not been achieved and that for a "quantum" computer to truly be quantum, it would have to use actual instantaneous non-locality to process

thanks for this discussion it's been helpful

Yes, EV maintenance can be about 35% cheaper than ICE... but most of this maintenance cost difference does not typically even come into play until the car is past the period of any extended warranty that the manufacturer would otherwise offer... by which time you've finished paying for it, and can afford the extra couple of thousand dollars per year for maintence. EV's are more expensive up front, and the costs that you save on gasoline, the only significant cost for the first few years of ownership, are not as much as the price difference you'd have to pay on financing for the same amount of time as you would have financed a less expensive gasoline-powered car that was the same size as the EV you might have been considering. You can push out the payments over a longer period to lower the overall monthly burden and make it more financially attainable, but then you are making it take even longer before you actually will be begin to break even.

Not long after that, you would be looking at replacing the battery on an EV, which will chew up several more years more of gasoline and maintenance costs. In practice, you are not going to see any savings at all until well over a decade of driving it. Many people don't even drive a single car for that long.

The future maintenance programmer will be most likely better educated

{snark} They can learn it all while riding in their flying car {/snark}

I see no evidence of an increase in such education over time. Statistically, programming is a dead-end career such that investing in high-end techniques may not pay off.
