If that is the kind of work published by academics associated with the MIT and La Pontificia Universidad de Madrid, then maybe I should not feel frustrated after all by not being an academic.
in English vernacular being a frustrated X (as in a frustrated academic, frustrated poet, etc.) means that the person is actually not that, but have in some way been prevented from being the thing (frustrated) and have perhaps rancor in regards to the frustration and towards those who actually are the thing (this second feature being sometimes implied depending on who is doing the description of the person as frustrated)
Thanks, I wasn't aware of the 2nd meaning. I also interpreted the "frustrated academic" as "an annoyed academic", rather than "an unsuccesfull academic".
I think maybe you made a typo in your OP? The authors assume beauty is decidable and use that to show that would imply that the halting problem is undecidable. It applies to anything, like you say, and to me it seems like a silly argument, but I think it’s a valid proof given the premises.
