I feel this comment. I did a masters with a thesis option because I was not hurting for money with TA and side business income, so figured I could take the extra year (it was an accelerated masters). Loved being able to work in that heady material, but disliked some parts of the academic environment. Was glad I could see it with less time and stress than a PhD. Even so, I still never say never for a PhD, but it’d have to be a perfect confluence of conditions.
