That's the usual definition we use for AI procedures.
The thing is, we settle for one line of Shakespeare, and use billions of iterations, rather than infinite monkeys.

A long time ago in a laboratory far far away I used to do Monte-carlo simulations of molecular surface interactions. Although the data was random (the Monte-carlo part) it had rules to follow.
Your proposal seems to just be feed a ton of random into a system and . . . well that's what I don't get.
Chaos begets chaos (localized pockets of order are implicit for true chaos as the sample grows large). Perhaps explain how your neural network will digest the information ?

1) Every byte is more or less a valid Z80 instruction.
2) Hence - if you have a real Z80 emulator to decode instruction and produce outputs as they should be then you can feed the same byte into ANN and from outputs produced by real emulator calculate error of network and back propagate.
3) So a 1 GB is not garbage. It is simply 1 billion Z80 instructions (little less due to the fact that some are 2 or 3 bytes long). You could limit feed to only valid instructions. But for the ANN to learn Z80 alone you do not need to interpret multiple instructions together (i.e. the whole program). You can train the network instruction by instruction and each byte is a self-sustained perfectly meaningful sample.

I still don't see what would really be learned from a scillion randomized one-byte instructions. If they're all essentially Z80 instructions 'as is' then they all would be 'true' - and so the result for the training set would be, in Carribian style: "It's All OK".

Not all instructions are one byte long; you could insert a 2-byte or 3-byte instruction(s) to training samples. And there would be multiple outputs as described earlier.
Imagine emulator like this:
case clear_a_instruction:
setflag(z);
clearreg(a); /* write data value 0 to register a */
break;
case clear_z_instruction:
setflag(z);
break;
...
Neural network would have following outputs (each 1 bit):
- output to say that we are writing data
- 3 outputs, each 1 float, to say what is the source (7 possible registers)
- output to say we want to set zero flag
- 8 outputs for data
So when our neural net obtains a byte with value "clear_a_instruction" it's output would be:
a) output setflag(z) set between 0.5 and 1 which means it fires,
b) output for write to register set between 0.5 and 1 which means it fires,
c) three outputs for registers set so that it fires 'A' out of them,
d) and data bits set to < 0.5 which gives binary 0.
So you would do a write operation with source = 0, destionation = register A, and set the zero flag. Which is what this instruction is supposed to do.

Well - I admit I'm not following - or it seems that the neural net already has been trained. That is, effectively, a rule set.

You did say a gigabyte of random data, did you not? One does not insert things into random data, deliberately, and maintain calling it random.
Perhaps you're trying to seed code in a sea of random data in order that the Neural Net will learn how to find it? I could see that as a way to search for messages or embedded code.
But, as I started out - I guess I'm not following your vision.

My fault, I am not a native speaker. Perhaps it is better to prepare a small sample and come back later.
Just one last try, simplified case of fictional processor with just four 8 bit registers and only 8 bit instructions that only affect these registers and nothing else.
So...
1. Neural network outputs can be from 0 .. 1. These values are float. This means that a single neural network output can -for example- assume value between 0 and 255 and even 0 and 65535 (if you want to represent values from 0 to 255 as values between 0 and 1 then you use n/255 for value n and 1 for value 255).
2. This means that a single neural network output can represent 8 or 16 bit register. For simplicity let us assume our neural network has only four 8 bit registers: A, B, C, and D. So we have four outputs.
3. Now let us feed neural network with 10 sequential bytes. Since values to feed the net are 0-255 we can use one single input for that (...or 8 inputs, and feed them binary pattern, it is a matter of choice).
Structure of ANN: so let us have 8 inputs, we have 4 outputs and we have (let's invent it right now eight invisible levels, each one 8 inputs.
4. We now produce an emulation software (not a neural network, but a real emulator) for this fictional processor. And we execute these 10 sequential bytes on the emulator. Emulator will interpret instructions and correctly set the four registers after each instruction.
5. Now we have possibility to train our network. We feed it one byte. We then feed the same byte to the emulator too. Emulator provides correct value for each register after instruction. Neural network provides output. We calculate error (as difference between correct value and ANN output) and back-propagate into the network i.e. update weights.
6. Now we feed neural net with 100.000 random instructions (bytes) and we do the same with emulator, back propagating after each byte fed into network. The assumption is that after this training the neural network will actually know how to emulate our fictional processor and will produce correct values in registers (4 outputs) based on input (8 inputs).

OK, let's simplify AI training*:
0. You have data. You might have an idea what it means to you, but it's really only ones and zeroes.
1. You stream this data into a neural network/backprop routine/whatever, which does something (it doesn't matter what) with the data and gives you output.
2a. If the output is useless (99.99999% of the first very many iterations, if you've got it right), you tell it "That output is not useful" (in a coded manner, of course).
2b. If the output is useful, you tell it "That output is useful"
3. Rinse and repeat.
Eventually, you get quasi-self-written code that does exactly what you want it to do, and actually does better than you could code it, because, as in facial recognition, where you'd need a hundred billion lines of code to deal with every possible detail/angle/lighting effect/mm of hair growth, it can just look at a face and tell you who it is.

That's pretty much how genetic algorithms do auto programming. Only they combine useful programs in hope that they'll become even more useful.

Nowadays you see lot of people walking around staring at their phone screen as if their life depends on it. My wife suggested we should sneak up to them and scream loudly "pikachu..." and then pretend as if nothing happened.

Why not take it to the logical (and sincerely deserved) next level. Up your game.
If you or a friend have a canine companion or feline friend, cast some of their dropping abundantly before the phone-zombie. Not as startling as your plan but most definitely more persistent a reminder of the risks they've been taking (and lost).

From an email from my aunt: This morning, when I turned on the computer it did over an hour's worth of updates - things looks different and I am trying to figure out how to hide this annoying Ask Me Anything Cortana thing at the left bottom screen. Right now, the Olympic medal count just popped up at the left as well. I'll have to ask Mr. Cortana how to make that (and him) go away.
Wow, Microsoft is pushing medal counts onto the desktop? How pathetic.
