Programming changed all along.
New concepts came out all along.
They became standardized all along and came down market to smaller and smaller projects.
Source control.
Cloud.
Agile/Scrum.
Code completion IDEs.
Higher Level languages.
These were not LLMs but did represent a shift that had to be kept up with.
LLMs are no different, just a bigger jump.
There is just as much opportunity here.
Software development and software developers are not going away.
More software that never could be built will now be built.
For the forseeable future there will always be software that needs to be overseen by a human.
