In my mind we will have a bimodal set of skills in software development, likely something like a product engineer (an engineer who is also a product manager-- this person conceptualizes features and systemically considers the software as a whole in terms of ergonomics, business sense, and the delight in building something used by others) and something like a deep-in-the-weeds engineer (an engineer who innovates on the margins of high performance, tuning, deep improvements to libraries and other things of that nature). The former is needing to skill in rapid context switching, keeping the full model of customer journey in their minds, while also executing on technical rigor enough to prevent inefficiencies. The latter will need to skill in being able to dive extremely deeply into nuanced subjects like fine-tuning the garbage collector, compiler, network performance, or internal parts of the DOM or OS or similar.

I would expect a lot of product engineering to specialize further into domains like healthtech, fintech, adtech, etc. While the in-the-weeds engineering will be platform, infra, and embedded systems type folks.
