Also, as they proliferate, they're going to have to deal with vandalism. A gas station is a neatly concentrated resource with oversight, security and even they still get vandalized.

Don't whiz on the electric fence!

Things like pricing can always be messed with. I think the maintenance issue, as the network grows, will become challenging. We'll see, though.

And in 1900 the same arguments applied against gasoline cars and you could get food for your horse, have a stable to keep it in, find a blacksmith to put new shoes on your horse, etc. just about anywhere.

The technology for EVs is still pretty early and just starting to improve. Give it another 10 years and it will probably address most of your concerns.

Win.ini could only offer things if the core was already exposed in config.sys and autoexec.bat; 32-bit drivers could not be loaded by Windows and it was pointless to load drivers for windows only as it was easier and more stable to targe DOS.

win3.11 didn't have it's own drivers besides netbeui and other windows crapola but it required a tcpip and network drivers to be loaded in DOS.

Win95 did also have win.ini but already had 16 bit driver support and a registry. However most things still had to be loaded in DOS. This didn't change for desktop systems until windows XP. So when it came out there was no driver support for anything.

The Linux kernel does have a relatively stable API for drivers, I wrote a USB driver for kernel 2.2 which still works for 2.6. Most drivers do not change, there are several in source that work and haven't changed in a decade. Even old nVidia drivers work with current kernels. If you want a binary driver, you may have to write your own shim but that's trivial if you're really bent on protecting your imaginary property.

Some things change but these days all of the common stuff is stable. Sometimes stuff had to be fixed to conform to standards, that happens in windows too although windows rather breaks the standard to support legacy and expects everyone to follow a broken design.

It might keep a few out but there are people who get their jollies out of trolling and the outrage that they create and might be willing to pay a few bucks for their hobby. It's been going on at least since Usenet (mid 80's).

I do enjoy small scale discussion on Facebook. I usually limit people who can post on my comments to friends of friends and that keeps the discussions more civil and usually more relevant. Perhaps the real problem is just that the number of people who can post a comment on many discussions is just too large. There is the risk of living in an echo chamber, though. Maybe a discussion site that creates groups with a representative sample of views, etc.

They get an unlimited bonus structure so that there's no limit to how much they will sell. Sales people are greedy bastards and they will follow the money trail management creates, regardless of whether it is good or bad for the company. Structuring the sales compensation is very important - I've seen many instances where the salespeople are doing things that are not good for the company but maximize their payoffs.

Why do sales people wind up in charge? Because they sell everyone else on how wonderful they are. If you don't have a management team with some real knowledge of the business you will wind up with self-promoters running everything.

I'm an engineer who runs a business. I know the tradeoff between technology and costs. And figuring out how and where something should be validated is not a "business decision". It might be a business process decision, but unless it affect the bottom line (for example, the validation costs $50 so we only do it when a customer is just about to purchase) it's not a business decision.

There's a real problem with engineers not understanding business just as much as there's a problem with business types not understanding engineering. I had one of my engineers say to me once "I don't understand why we have sales people" (hint for those of you nodding along with him - it's so we get income so the engineers and everyone else can get paid). I've seen companies where engineering gold-plated the systems architecture to the point where the company couldn't make money with the deployed hardware.

Business isn't all that complicated and anyone competent as an engineer should be able to understand it (you may not like it but that's another issue entirely). Figuring out how the costs of a system affect the business, how the features in a product affect its salability, these are things that a good engineer will understand, and will probably wind up explaining to the business people.

Think different!

Maybe instead of stacking the chips, you put one on the bottom and have it double as a backplane and then mount additional dies to it vertically (like itty bitty expansion cards). Then you can get some airflow or other coolant flow in between those vertically mounted dies.

These kinds of funky solutions will only show up when they're cost-effective (that is, absolutely needed). The reason we stick with flat dies (and single die packages) is because it's cheaper to make/mount a single die in a package. However, when the performance is really needed we'll start seeing some innovative solutions.

There have been plenty of concept designs and current chips use 3d technology to an extent. The problem IS cooling. On a flat plane, you can simply put a piece of metal on top and it will cool it. Current chips sometimes stoke away close to 200W. With 3D designs, you need to build-in the heat transfer (taking up space you can't use for chips or communications) in between and both planes will produce equal amounts of heat so either heat transfer needs to be really, really good or you need a heat sink several times larger than the space you'd save in between the planes.
