Maybe it was never the bottleneck for paid software engineering at incorporated entities but it was definitely, 100%, the bottleneck for most human people.
And now instead of having to get the help or code from an actual programmer, as a non-programmer but technical person, I can generate or alter any small trivial applications I want. I'm not going to be writing an OS or doing "engineering" but if I want to write a GUI widget to display my PCs temps/etc, or alter a massive complex C++ program to have some feature I want (like adding checkpointing to llama.cpp's fine-tune training), suddenly it's trivial and takes 15 minutes. Before it'd take days if it were feasible without help at all.
