"When I talk about shifts, I'm referring to things like the proliferation of smartphones and tablets, which increase the net-demand for software and along with an entirely new specializations of knowledge."

iOS was basically AppKit, so anyone already developing for the Mac knew most of what they needed to know to develop for iPhone.

Pretty much every programming innovation is incremental, and doesn't require throwing out all of your previous knowledge and starting over.

Maybe. But AppKit was not the Mac Toolbox.

When my career began being good at memory management was a skill to be proud of. I would say now, being good at concurrency is a skill to be proud of.

I don't really have to worry about memory management any longer but didn't worry about threading when I started my career.

As I see the younger generation entering the programming field I wonder in what ways the craft will be different when they've had a few decades under their belt.

Will parameter tuning datasets for machine learning be the coveted skill? Who knows.

But the demand for developing in AppKit suddenly increased by orders of magnitude.
