I was explicit about what the real argument isn't: the notion that lattice cryptography is under-studied compared to RSA/ECC.

I understand what your takeaway from this thread is, but my perspective is that the thread is a mix of people who actually work in this field and people who don't, both sides with equally strong opinions but not equally strong premises. The person I replied to literally followed up by saying they don't follow the space! Would you have assumed that from their preceding comment?

(Not to pick on them; acknowledging that limitation on their perspective was a stand-up move, and I appreciate it.)

You do "XYZ isn't the right argument, ABC is" on a thread like that, and the reply tends to be "well yeah that's what I meant, ABC is just a special case of XYZ". No thanks.
