Problems how often and how sever are a design issue. In current Gen IV you have GFR's that use helium as a coolant, it floats and is unable to stay radioactive for long, Compare to a Gen II with water it stays radioactive for a long time. Gen IV plants can use previous gens waste as fuel, some of the design are fairly proliferation resistant and that is a HUGE issue with helping the third world skip the industrial use of fossil fuels for power and heat.

The point is we got stuck on gen II plants, Gen III has come and gone and were just starting to see ground broke on gen IV plants.

Insurance is about the hype, fact is you get more exposure being downwind from a coal plant sure people are scared but thats because others told them to be.

A lot of these issues they have brought up as vehicle error was actually human error. "runaway acceleration, unexpected braking" That sounds like the person may have temporarily got their mind twisted and hit the accelerator where they wanted to hit the break, and vice versa. Most of the time when our brains get twisted, we quickly resolve the issue. But I remember resting my hand on a Soda Bottle while driving, a car with automatic transmission, and when I was driving after hearing the engine at a particular RPM with my left foot I tried to reach for a non-existent clutch, my right food off the accelerator. I hadn't drove a car with manual transmission for about 5 years, but a particular set of sentence tactile, audio, visual. Triggered a reaction that I wanted to change gears.
The problem is a temporary lapse in judgment, can cause particular effects. And there are enough people who will be too afraid to admit that they made a mistake would blame the technology.

If by for some reason your car is having runaway acceleration, instead of driving a herroing tail at high speeds like in the movie Speed 2 but only with a land base motor vehicle and not a boat, you shift the car in neutral, and break/parking(emergancy) break. You can do this while the car is in motion for Standard, Automatic, even Hybrid Cars.

You used the standard dictionary definition of waterway. But the EPA has expanded their, correct in my opinion, oversight of actual waterways to include standing water and even temporary bodies of water from storms. A willful expansion of their power. I think they are giving themselves a club to use against farmers who do other things they don't like but can't stop through their current regulations. So they bogusly expand the regulations they have.

There was a period in the early 00's when one of the my company's manager would periodically walk through my office door and the first words out of his mouth was "I just read about this patent..." and I'd stop him right there.

"This is going to be one of those things where the extent of the filer's 'invention' was to take something people were doing with LORAN fifty years ago, cross out 'LORAN' and write in 'GPS', isn't it?"

"Well," he'd begin.

"I don't want to hear about it. It's guaranteed to be invalid on the basis of obviousness, but if they get lucky in court and I've actually read or even heard about that specific patent they'll be able to take us to the cleaners."

You'd be amazed at some of the technology patents the patent office grants. Stuff anyone who'd been a practicing engineer for more than a few months would laugh his ass off at if he were patent examiner.

Microsoft has to prove that they won't mess up the smartphone like they did with the desktop. Consumers who use Windows do so because they have to not because they want to. Microsoft never was able to get a strong foothold in the mobile market, because there was too much bad feeling about having to use Windows on their PC. With the problems that were prevalent during the mid-late 1990's still sticks in people head.

Blackberry biggest mistake was not being more developer friendly. Once apple allowed for custom Apps, and Exchange compatibility, that started to put a nail in blackberry dominance.

How it was initially deployed is known only to its makers, but Stuxnet was designed to enter an isolated facility on a USB drive. Once on the LAN it would propagate to other computers, and potentially to other networks via an infected laptop, which is how it ended upon the Internet.

You can use your imagination as to how they got the USB into the target facility. It might have been as simple as dropping the USB stick in the parking lot of a vendor, but given the resources needed to create the worm itself you can't rule out some kind of black bag job or human asset.

If someone gains root, they can swap out the on-disk boot image that contains the kernel, and wait for someone else to reboot it as part of normal maintenance.

Assuming there isn't something that prevents the boot image from being replaced. See my other, more extensive, comment in this thread.

I really don't see that as a the most vulnerable point. Not by a long shot. Tapping a digital fiber link wouldn't be like US submarines tapping Soviet analog telephone cables. The data on the link can be encrypted and authenticated at either end such that it's not really practical to modify or impersonate without the kind of assets in the organization that would make an inside job a lot simpler.

The real problem is human factors. Air-gapping sensitive systems is a sound idea in principle but in practice it often fails because it's too cumbersome for users who then undermine the system. And Stuxnet showed that it's possible for a sufficiently advanced opponent to target systems of the far side of an air gap.

So the problem is with the notion that separate parallel systems separated from the outside world are a "simple" solution. They're a potential solution, but if you want to have confidence in that solution there's a lot of work analyzing and policing the behavior of the people who use, maintain, and produce the equipment.

Parts that positively cannot be assembled in improper order will be.
