If you like deterministic things, you will not like medicine. Perhaps the most deterministic part of medicine is orthopedic medicine because orthopedic doctors can treat the structure of the human body in the most (relatively) mechanistic way, but even that is limited.

Human Machine Interaction is an art (or craft, if you prefer) not a science. So the size of the code dedicated to the user interface can easily be orders of magnitude larger than the fundamental business logic they interact with. So there will likely always be a lot more work there.

Then other areas of computing that are not deterministic yet are very scientific, like Data Science, which is probablistic as opposed to deterministic. Which is an almost 180 degree flip in your mental modeling.

The class sensitivity you exhibit is astonishing. Especially for someone your age. I really think you aught to do some soul searching there. Classism is an objectively bad thing to indulge in.

As far as the loneliness is concerned, well, deterministic work tends to be cut and dried and narrowly proscribed. So, say, writing a device driver for an OS will not require you to interact with people because the work can be specified exactly. Increasingly deterministic work will be outsourced to machines too. They're spectacularly bad at interacting with humans (just ask Alexa ;)
