Binary data formats may sound geeky and complicated to you, presumably because you haven't bothered to try it, but binary is actually simpler than morse code, which you apparently believe to be sufficiently simple and accessible. If there is a signal encoded in binary, then chances are fair that CHILDREN can figure it out. When you say things like "phd's in Computer Science", what you convey to people around you is that you don't understand what people are doing or why and you're not interested in knowing because you think it's over your head and if it's over your head then clearly FDev wouldn't do that because you think Elite is a simple game for kids.
Give yourself more credit than that and dial back the ignorance. Binary is a simple concept that you can learn in a few minutes (much quicker than you could learn morse code), and maybe it opens up new ways for you to think about the UA tones. If you're not interested in putting in a few minutes to learn something, it's fine if that kind of puzzle doesn't appeal to you, but you should at least be aware that your assumptions are poorly grounded, and that your limits are self-imposed.
Slow down there, hoss. I was simply trying to convey the idea that in-game systems already use Morse Code, so it's a known quantity. ASCII is thus far, not.
And for the record, I'm a software developer in my day job, so nothing in these discussions has yet to get too technical for myself. That may not be the case for others, though.
