They do have a master's degree according to the post.
The claims made are not that deep for researchers.
The use of the word masters is now considered not cool according to Stanford... :-)
It's not like I have been doing many things outside reading papers and books over the past few years... The post that person used as an ad-hominem even says so.
Ad-hominems are not a particularly nice way to argue about correctness of a claim.
Maybe you know something but I don't, but I believe the comment you are replying to was a compliment and not a sarcastic dig.
This person has made a similar remark and purposefully looked into my post history - which doesn't make any claims about my knowledge or skills - lied about it, and made a sarcastic remark, see "everything".
