That's fair don't get me wrong but Go is muuuuuch easier than the machine code or C they used to be stuck with and requires no manual garbage collection for example... so much stuff modern languages do automatically you had to do from scratch in C.
Ain't this is without even mentioning LLMs... I know for a fact many devs are writing great chunks of their code with ChatGPT. GPT-4 in particular is very good at it.
Garbage collection is a good example. Automatic garbage collection is always a tradeoff between efficiency and use of resources, i.e. cpu time and memory usage. It can only do educated guess when it might be the best time to clean up memory, so it might do it even when there are better things to do for your cpu or it might not clean up at all of you still keep a reference to am object somewhere without you noticing.
What high level languages really brought us is efficiency in development time (you can develop complex code much faster than in the past), but not really in resource usage.
This varies highly with the language. It's absolutely a fair criticism of Python for example. But I use Go as my example precisely because of how efficient it is despite being almost just as easy to code.
