I have spent a frustrating 'day' reluctantly doing two main tasks:
1/ Purchasing/speccing parts for an experimental electrical build.
2/ Working with the suppliers of a failed piece of electrical hardware to get a warranty replacement commissioned and working as required.
In both cases I have been dealing with Chinese suppliers because the price &/or availability makes them the only real option.
In both cases the documentation is woeful and so I spend too long in back-and-forths. "How do we do x?' 'What is Y?'. 'The old one had these same settings and worked, what is not right here? How can we even tell?'.
This is the price of cheap. It is not because it is Chinese but because it is cheap and that is sadly what we value. Cheaper is not better value.
I am not a coder but I feel this is what coders are worried about with the advent of AI code. Stuff that seems cheaper but is a joyless pain in the butt to maintain & work with.
