Yes. Deploy the sexbot, maybe it will be more fun than the screaming teacher

.
More seriously, I don't see this as a big problem. The problem was always school for all the reasons I've written about. And assuming there is no teacher in the room, maybe the place will become a little softer on the students. The robot won't run around and beat you, or try to humiliate etc. Unless such functionality is coded into it which I doubt.
As for lost jobs, we can't pretend the job system is viable anymore. But that is not really specific to the school sexbot. It leaves one less occupation which is amenable to strikes, which is sad. But again, not specific and the fact we will need a physical revolution (kicking out the people in power or somehow making their influence irrelevant) was obvious for a long time regardless.
The article also complains about surveillance as if it hasn't been around for decades. School always tracked attendance even before digital tracking was in. Then came CCTV, then police, transparent backpacks, RFID tracking, automatic notification of parents, blah blah. The sexbot will perhaps make it easier to track and / or track more things (like what questions students were asking), but still - the problem enabling tracking is the oppressive institution of school. It "needs" to track attendance so it can punish kids for not coming and teach them their life isn't theirs early on. It "needs" to track behaviors so it can mold them into the state's perfect puppets. Yet I suspect conservatives (and most of everyone actually) will focus on the sexbot and ignore the fundamentals of school. Oh well.
Someone will probably want to say that the sexbot is uniquely bad because now the "elites" (whoever they are) will be able to automatically put in it whatever educational program they want to insert into the students. I can see this argument yet this is basically what happens today already. There is a "curriculum" and teachers cannot affect it in any significant way. They can strike, which I've already covered and they never strike in favor of the students anyway (students have no effect on it). Actually, they don't even care about the curriculum but about the pay, usually.
To play devil's advocate against myself, one
actual bad effect that could happen is getting kids used to be "directed" by robots or being under the authority of ones, which will make them more amenable to accept police bots etc. But truly, we've lived in an authoritarian world for a long time regardless, and police bots have been in since a while. And again, eliminating school fixes this too.
