Well, considering that now we have the internet and 'all the knowledge' at our fingertips, we have a pretty good idea as to what most people would do.

Do they really download music and sound theory? Do they learn about acoustics and patterns? Do they really learn about painting and creativity?

You are all dismissing an important factor; recreation.

People would want to escape that world even more than they now want to escape this world. Therefore, all kinds of escapism, from porn to video games to movies to different hobbies would be even more popular than it is here and now.

Think about cellphone zombies, glued to their phones, playing candy crush.

Think about the WoW-addicts, that can't stop playing those MMORPGs, because they enjoy living in a primitive 'virtual world' more than a detailed 'real world' (fewer limitations, considering you fan teleport, portal, fly and do magic in the virtual world, but doing any of that in 'real world' would be cumbersome at best, if it can be done at all).

If we consider things like 'Oculus Rift' and vast amounts of entertainment produced in all kinds of ways for all kinds of platforms, from tablets to cell phones to computers to video players (regardless of format, from DVD to Blu-Ray to mp4 and avi files), and then realize what kind of video games exist, from Atari 2600 games to Commodore 64, Super Famicom, Sega Dreamcast and onwards all the way to the modern consoles and powerful PCs with the expensive and powerful graphics cards, we can realize, there is SO much, such a vast world that exists already in the 'recreation' scene..

..that it'd be absolutely stupid, foolish and unrealistic to assume there's no recreation that utilizes the implant / Matrix-technology.

The 'Lady in the Red Dress' was just a subtle hint in this direction, but if we imagine a world without the war against the machines, where people can just live 'freely in Zion', the people without implants would basically be living the life of people of seventies without computers or cell phones.

Think about people, who do not have computers, cell phones, or any kind of 'smart tech' in the modern world. How much would they be missing out on? How long can such people even survive?

Soon all manual jobs will be done by robots, from cleaning to trucking, to mining and such. Then where will those technologically 'challenged' people be?

There is a Twilight Zone or Outer Limits-episode about this - pretty much everyone is plugged into a supercomputer and can know and research anything immediately, but there is one guy that can't do it (I can't remember the explanation), and he loves books and reading, but just can't keep up with this 'instant knowledge' system.

Of course the supercomputer becomes greedy and crazy and starts using people that are plugged into it, to feed itself more and more information, and this makes some people lunatics that want to know how many hairs they have, and so on.

I think it's a realistic depiction of the contrast between humans that are plugged, and humans that are not, even though otherwise, the episode is a bit ridiculous.

The thing is, though - this whole thing brings up the problem of the holodeck. If you can live a perfectly believable, completely realistic simulation of your 'ideal life', why would you ever leave it?

Why would you unplug from that simulation just to go to the depressing underworld of 'Zion', with all the noise and dirt, no nature, no fresh air or open skies, and talking with mongrels who have no experience of what it's like to be plugged in, and who have no way to know all the things you know, and can know easily?

Why would anyone make that choice, except for curiosity or just to see what it's like? It's not like the 'plug'-people and the 'no-plugs'-people would ever truly and completely mingle with each other. They have nothing in common, except their physical bodies and that they happen to exist in the same environment. The others can always escape into a 'perfect world', and know anything, do anything, and know how to do anything, while the others... can't.

The reason why Tank and Dozers were bodybuilders, was simply that they have nothing else to do or occupy their time but to go to the gym and try to satisfy their bodily needs, since intellectual stimuli or knowledge is out of their grasp. All they can do is pump iron and have sex and reproduce, and that's about it.

They live in a depressing, dark world, where food is awful, bad-tasting goop (though this would not be healthy food, as there have been studies where people have given nothing but 'everything the body needs according to science', and those people nearly died - you need LIFE in your food, which is why you can't stay healthy eating food that has lost its own health), where light is limited, and where they can never play the latest video games that the plug-people are enjoying.

This world would realistically almost never see the "plug-people", because they would be plugged in most of the time, while robots exercize their bodies and feed them nutrients (or even that goop), while they experience eating gourmet meals in fine restaurants.

These people that can live -ANY- kind of perfect, ideal life, would pretty much never unplug from that to mingle with the 'no-plug'-people, because the 'real world' would just be a nightmare to them, considering their every second spent in the virtual world would just be so full of euphoria.

Even their social life could be exactly as they want it, so they have no need to interact with ACTUAL people, that can be temperamental, judgmental, harsh, violent, and so on. Just look at what's happening with universities and 'safe spaces' and such. People already want to escape the realities of actual social interaction - this tech would make it perfectly realizable (this is probably not a word, though).

I bet most people would basically even forget their situation, after being plugged in for years without having any need or reason to be unplugged, if it wasn't for -some- kind of control that forced them to come out of it every now and then.

I think a reasonable thing might be that everyone has to take turns in powering the machines that create the power, electricity, virtual machines, etc. and produce that food-sludge that they have to eat. But then, we have been shown that their tech, although dirty and in some ways primitive-looking, is actually quite advanced, and everything could probably be automated.

In the end, I think the 'organic' people would sabotage the plug-people, by unplugging them, shutting down their computers and machines, or sabotaging the electricity production or something.

The situation would probably escalate until the 'plug'-people would realize that the no-plugs'-people would be a threat to the stability of the 'plugged-in-utopia', and when everything is automated, and robots do all the work, there's no need for 'natural people', and they would be either imprisoned or eliminated, just so the 'plug'-people can continue their 'perfect lives' in the virtual world(s), and in the end, the whole human race would just die out, because no one would be having sex in real world, when they can have much dreamier sex in the virtual world.

There might be some 'plug-people' that try to help the non-plugged ones and teach them things, meditate with them and such, but it wouldn't be enough to keep them from basically rioting and becoming the threat the system would think they are, and sealing their - and the humanity's - destiny.

Hm, this might make for an interesting movie, actually. Some people arriving on this planet and finding all these skeletons strapped to machines that plug into their brains, and lots of other skeletons with no plugs whatsoever, and wondering what happened.
