I don’t think the Indus Valley seals are a script at all. They might be more like corporate logos.

Try deciphering the english language from a bunch of billboards and pop/cans. Even if you figure out the alphabet there aren’t enough words to construct a single sentence.

All the AI in the universe won’t help when the problem is lack of real data.

Well, names and titles are still language, but I agree with your actual point: the Indus inscriptions seem to be too short and probably not general enough to allow an in-depth understanding without finding new, longer texts.

That was Sproat et al's point. (Sorry, I can't remember the other authors, I just happen to know Richard Sproat.)
