The global economy currently relies on humans working to get what they need to survive. The global economy needs to change in a way that makes it so humans can receive what they need to live without having to work, since there will eventually be no jobs a human can do better than an AI in a machine. I seem to be the only one in my classes who thinks about this. My economics teacher thinks this is too complicated of subject. I thought macroeconomics was a place to talk about this, apparently my teacher isn’t thinking about this kind of stuff either.
No, you misunderstand. Your economics teacher's job is to teach the fundamentals of economic theory. He certainly does think about those things, but it's his job to keep the class on the rails and prepare the students for the exams. I pretty much bet that
every year there's at least one student in (his/her) class who wants to talk about some side topic and how it's super-important to macro-economics, and he had to steer the class back onto the rails.
Your teacher is actually taking the "big picture" in that sense - there are literally a million topics that have some relevance to macroeconomics that
could derail his class from the job of teaching the basics of economic theory, and he probably hears a different one every year based on what's trending that year. What you're talking about is
applied economics, but you should take the tools from the class and then apply them in your own time. It's not the job of a macroeconomics class to be a mixed bag of exploring
every single issue, it's the job of the class to teach you
the macroeconomic approach to analysis. Also, presumably people are paying to attend these classes, so yeah, taking time away from the main task that's on the actual exams isn't really helpful. Also:

Professor Gardner Ackley makes the distinction between the two types more clear and specific when he writes, “macroeconomics concerns itself with such variables as the aggregate volume of output in an economy, with the extent to which its resources are employed, with the size of the national income, with the “general price level”.
Microeconomics, on the other hand, deals with the division of total output among industries, products and firms and the allocation of resources among competing uses. It considers problems of income distribution. Its interest is in relative prices of particular goods and services.
So, the stuff you actually wanted to talk about is more on the microeconomics level. Macroeconomics is a specific tool, and it's for specific things. It's wrong to try and shoehorn other topics into that, because that's not what the tool is intended to do.
