My bet is that engineers will have to go down, closer to the silicon level. The higher-level stuff will become more and more accessible to the non-tech consumer, so building apps and stuff will no longer require tech-savvy people, everyone will be able to make their own app.
i'm a low-level developer but I disagree, low-level C or chip design or firmware development are actually a lot simpler than (complex) app development, AI can take over low-level way more easily than upper level sw devel.
