What about the 1-1 relation between the binary encodings of ASCII-characters and their base64 equivalents? I dunno, but isn't a base64-encoded character sequence still unambiguous / aren't the encoded character sequences formint a prefix-free grammar when concatenated?

Still very impressive.

What's even more interesting are the edge cases as presented above. Now that we consider almost-perfect natural translation a given, we're obsessed with marrying this to basic rule-based logic.

Me too, in every conversation I had with ChatGPT.

Because marrying the two seems almost magical and scary.
