Probably because names kinda obfuscate the ridiculous impracticality of this exercise. This microgpt can produce a random sequence of letters and by chance it might look like a name. If the thing output, let's say "Kianna" you just think "wow, it IS a name" but is it though? (Idk if it's a real name, at least not in Spanish) Isn't a normal word, so the randomness of names helps to hide the fact that this gpt just outputs random shit that looks like names. If you just use words you will get mostly random shit that doesn't resemble any real words. Just my hypothesis. I can see the convenience of using names. The output look like real names but you can achieve the same result with old ai and very basic algorithms.
