What were the actual questions? Was it worded to elicit no's? Did the respondents understand the question?
What was the definition of "major security breach"? Was the threshold so low that things like not changing a password every 30 days is a major security breach? Who responded to the survey? Were they people who only see low level issues?

Surveys can be tailored to get any desired response.

Security systems need to work for everyone not just you. The more "special cases" the weaker the security is.

Oh, and if it breaks the database, that's your problem.

If renaming a server is not easily fixed by a config change then whoever wrote the system is an idiot. Sorry but we can't deal with your and the other 20 naming schemes that individuals though were "cool".

We just patched all the servers for greater security. Too bad you can't use your software to control or monitor them anymore, but that's your problem.

If you are relying on a outdated control or monitoring software it is your problem. Your software may even be using the security flaw.

Due to a breach, everyone must change their password. Too bad it happened while you were off for a few days and needed to log in for an emergency, but that's your problem.

This is exactly the same as a person forgetting their password in an emergency situation. If your system can't handle it then it is your problem. Should we leave the leaked credentials valid till we contact everyone in the database? Even those on holidays who might be unreachable?

You are using a very bad model to think of the electrical grid. It is not a huge pool where electricity injected anywhere on the grid is instantly available anywhere else on the grid. I call that the lake analogy. It is much more like a canal system with specific capacities between specific points and each canal has to be keeps full but not overflowing. Even though the grid may theoretically be balancing input and output there will be local shortages/oversupply because electricity takes time to move.

Here is a graph of California renewables output. The Wind line is not very smooth even though it is an average and there are no major storms going through which cause more fluctuation.

Also no one has ever made a cable anywhere near that long. An electrical conductor can weigh upwards of 3/4 of a ton per 1000 feet. The conductor alone could be 20,000 tons. Stronger yes, strong enough to support the weight of 30,000 feet plus the weight of the conductor plus the pull of the huge balloon? Doubtful.

Intelligent appliances,

Which no one has and no one is buying.

and it can pre-chill when spot prices drop.

Most of which is lost when the door is opened.

Same for the heating element in a clothes dryer.

This has to be the stupidest. You can't pre-heat a cloths drier that you may or may not use? Keeping wet cloths around just in case the price of electricity drops is not a good idea. Mold and mildew grows quickly.

Intelligent car chargers can not only adapt to fluctuations in supply, but they can even feed energy back into the grid when the price spikes.

Which is a real pain if you need the car and the battery is not charged.

Smart devices can help a bit but they are not the "solution".

harness it at 30,000 ft and run a giant power cable

Here are some of the issues;
1. How heavy is a 30,000 ft cable that can carry the electricity? Probably tons
2. How strong must the cable be to be able to support itself? As the cable get stronger it also gets heavier and the baloon gets bigger which requires a heaver cable to hold it. It is an infinite circle.
3. How much tension will the supporting balloon place on the cable and turbines? As the balloon gets bigger there is more surface area and therefore more tension on the cable.

I doubt very much that one can build a 30,000 ft cable that can support itself, carry electricity and hold back a balloon large enough to support the cable and turbines. It is the same issue that is holding back the space elevator but on a smaller scale.

This can be fixed with flexible pricing of electricity. Charge more when electricity is scarce, and less when it is plentiful

People use electricity when they need to no matter what the price. We turn on lights when it is dark. We cook dinner at dinner time. We have showers in the morning or evening. We wash cloths when we have time. Little of this will be re-scheduled based on the cost of electricity. Are you really going to get up at 3AM to do laundry? I doubt it. Even if you have a timer are you going to leave your wet cloths in the washer till you get up? You might not remember and those cloths will sit for another ten hours. Are you going to skip your morning shower because it will cost you a dollar extra?

The other issue with wind power is that it can vary uncontrollably minute by minute. This is the kind of instability that needs to be leveled out by more storage. Storage has two functions; time shifting and supply leveling.

Look at what is happening now. Certain jurisdictions like California have peak and off-peak electricity rates. The demand is still high during high peak rate times. If you look at those two graphs you will see that price has little or no effect on demand.
