If you're traveling at or under the speed limit in Chicago, the police will follow you until you do something wrong. Their logic is, "He's going the speed limit, so he's being careful, so he's got something to hide." It's standard practice to do speed limit + 5 here.

(I'm not saying the logic makes sense, just that it's used.)

There's no incentive for the ISPs to fix the problem?

I think if there's a way to increase profits by reducing equipment costs, then there is an incentive. One of the original authors of the TCP/IP protocol just designed a stream router (as opposed to a packet based one) that will route orders of magnitude more data for roughly the same cost as a conventional switch or hub. [citation needed] If ISPs adopt the thing, they spend less money on upgrading infrastructure to meet need and make more money. Money is a good incentive. You can make just about anyone do anything for the right amount of money.

At the advent of the printing press, academic minds were concerned that people would become dumber. They thought people would fill their minds with useless knowledge instead of trying to understand the material.

At the advent of the internet, people were concerned generations of people becoming morons with no memory or knowledge at all.

People will continue to get smarter and more connected. Reliance on technology does have drawbacks, but to see only the problems provided by this technology and not the benefit is silliness, too.

English has remarkably little entropy. A letter in a sentence like this one has an average of 1.3 bits of entropy. To improve the secrecy and randomness of passwords, I recommend substitutions. Take, for example, 'A bird in the hand is worth two in the bush.' This can be mixed into, '@B1rdInTh3H4nd1$W0rth2InDaBush!'. Perhaps not as easy to remember, but after you've made a few passwords like this, it becomes second nature. In my experience, it also becomes easier to mentally 'chunk' passwords, so something like 'B3hold0bli1v1on1$@Hand' is fairly simple to recall.

Of course, this brings us to a rather interesting junction. The second sentence has more entropy, making it more resistant to cryptographic analysis. The first sentence has more letters, making it harder to brute force. (Though it has no numbers or symbols, but lets set that aside.) Which is better? Depends on your purpose, I think.

"Same with light-based scopes."

Not to be pedantic, but all electromagnetic radiation is light, just not the way we're use to hearing it used.

Infra-red light is still light. 802.11 radiation is still electromagnetic radiation. Whether it's an AM radio in an old car, a $400 cell phone, or a telescope in the sky, it's all the same medium.
