I'm not a coder but a sysadmin. 35 years or so. I'm conversant with Perl, Python, (nods to C), BASIC, shell, Powershell, AutoIT (int al)
I muck about with CAD - OpenSCAD, FreeCAD, and 3D printing.
I'm not a senior developer - I pay them.
LLMs are handy in the same way I still have my slide rules and calculators (OK kids I use a calc app) but I do still have my slide rules.
ChatGPT does quite well with the basics for a simple OpenSCAD effort but invents functions within libraries. That is to be expected - its a next token decider function and not a real AI.
I find it handy for basics, very basic.
