Know it all? I do that at work, tell people to RTFM. Basically, I wrote the manuals. And, I wrote the manuals so I wouldn't have to remember this stuff. What's the option for running the process against a whole customer? I look it up. What's the environment variable that has to be set for the command to run? I look it up. I found it out, and wrote down the information in a shared manual. SO I WOULDN'T HAVE TO REMEMBER someone else's bad scripting habits and inconsistencies.
They can spend a minute searching for it in the document. Or, they can spend an hour trying to get a-hold of me to ask me to spend a minute looking it up for them. Who's time is more valuable? Surely not theirs if they don't keep good notes, don't share them, and spend an hour looking for someone when it takes a minute to answer on their own.
No, I don't know that stuff. That's why I wrote it down. I'M NOT THEIR FUCKING RESEARCH ASSISTANT, their SECRETARY, their PEON, or their FATHER. They are trying to waste my time, like they do their own.
I put up with this from my boss. He can't even keep track of his own email messages some times. Put, I provide them with a smile. If someone is new and they genuinely haven't asked a question before, I answer and show them how to look it up on their own. A $17 dollar an hour contractor who can barely spell computer or read the screen will be shown the door all the quicker once they've used up their dumb questions.
Although I pretty much believe you're trolling, peaceful voyages would be comparable to a biologist from the midwest spending several weeks traveling to spend a year in Antarctica researching a microbe. Eventually, if a civilization develops enough, they will have the resources to satisfy their curiosity. However, it is just as likely they will be scavengers looking for pretty fur and make the resource extinct. In a long enough timeline contact is inevitable and one or the other will happen. Might as well make sure it happens gracefully.
If seti style contacts are established, any actual contact is likely to be through time-capsule type care-packages that take millenia to arrive. Maybe eventually carrying biological samples.
I imagine Stephen Hawking because of his celebrity status and his disability is developing some sort of persecution complex and is likely to view aliens in the same context. Yes, when we deal with enough people there will be a few bad eggs. And, the more people we deal with the more likely we are to encounter the really really bad eggs. But, we can't hide in our houses. The vast majority are good people and will help insulate from the bad. Hiding does nothing to insulate us, only leaves us exposed in a different way.
Don't forget, a good diamond is basically one big carbon molecule. A diamond's not only imageable, but you can feel/hold/interact with it.
What are you trying to accomplish? If you want neat and pretty, that needs one type of thing. If you are trying to organize the cables behind the computer, that needs another type of thing. If you are only trying to neaten the cables between computers, that needs another. You building a rack-room or want something professional? My only concern was getting in-between device cables off of the floor and above doors. Went to home depot, bought 1.5 inch PVC Pipe mounting clasps (used to hold pipes to walls), and suspended them 8 inches from the ceiling. Then ran the cables through the clasp. To manage power-cables behind desk, I strap-tied the power cables to the desk, leaving other ethernet/keyboard cables which will move around loose. If you want something to impress girls, don't think having neat cables counts. Most women that have seen the cables dangling from my walls are more than a little worried.... Keep meaning to string LED lights along them to make them look less disturbing.
