OK I'm going to take a punt on:

Charles Babbage is worth nothing

[Istaria]

Well solving CB, AC and AT as pseudo-simultaneous equations gives:

A = 1
B = 0
C = 4
T = 1

You mentioned earlier that the order these letters were used in doesn't matter in the slightest, which means if we're using the letters as numbers then it has to be a multiplication. But with B = 0, any multiplication will give 0.

But yes, by the above CB = 4 x 0 = 0, so Charlie is worth nothing.

Can I ask 4 the key please?


EDIT: Some other thoughts....

One clue mentioned that a "5 year old could do it" (or something to that effect). Given that Turing seems to be a reference in this, I'll jump to the following wildly improbably conclusion:

The 5 is a reference to the 5 digit binary code that Turing used for representing letters. I don't have that table to hand here at work, but it's also worth noting that Turing's convention for writing binary was to have the most significant bit on the RIGHT, not the left. So 4 for example would be 001.

How any of the above probable tripe plays into this is anyone's guess.

{or just look in the top right corner and it tells you that its worth nothing....}

So
AC = 100
CB = 000
AT = 001

 So AC+CB+AT = 101

But i still dont know what ask 4 the key means.

101 * 4 = 404 but that doesnt solve anything

[MinerFTW]

i would say this is the code.

AC = 100
CB = 000
AT = 001

101 * 4 = 404 but that doesnt solve anything

wow, we got there in the end, now take the solution (101), ask 4 the key and bin it!

[Istaria]

Let's go with this too:

001010011

same number, obeying Turing's convention.

[grunt]

110010000

100*4*1*1=400

[Istaria]

Question: Is the final answer alpha-numeric? Or just numeric?

[Astargath]

The key has to do with number 4 obviously but i cant figure out how, i tried 101 4 times and bin it but it didnt work

[Wendigo]

Maybe

110111000
110010100

[Istaria]

More (probably ridiculous) speculation:

101 in base 4 is 1211 which in binary is:

10010111011

Which is unfortunately 11 digits.

Assuming the answer is binary ONLY, then it has to be between 0 and 511.

Ofc we don't know if this is the case :/

Has it been confirmed that there is a letter in the answer? I see some references to the letter B, but I can't find the specific post.

It seems unclear, however, binary notation is written in many different ways:
