I'm certainly no fan of shutting people down for asking questions. I think we may be interpreting the context of the question differently though. The parent poster was recounting having worked as a math teacher, stressed out every day from the planning and grading demands of the job, working in excess of 12 hours per day, earning a salary low enough that colleagues without a spouse's income to help out had to work a second job - and who still has nightmares about being back in the classroom. And then moving on to a software job with double the salary and half the stress. I read it as saying teachers should be appreciated / paid more and the response as why are teachers still doing unnecessary grunt work, making lesson plans and grading papers? Isn't that dumb work that a software engineer could just solve for them?

(Also, following through on this, if such a solution - computers planning your lessons for you, so all you have to do is what the smart computer tells you to - were to become reality, the lack of teacher appreciation / salary, which was the main point of the parent comment, would not improve at all - it would likely get worse, with teachers getting paid less for fewer available jobs. The deskilling of labor would probably follow, reducing teacher roles to individual, specialized, repetitive tasks, since it saves an enormous amount of money if low-skilled workers can simply be swapped out if they don't work out.)
