It is also intellectually dishonest to strawman an argument.
I didn’t say it is impossible to do X with FP - I said it is not necessary to do X in FP.
You can convince yourself of that by looking for larger-scale non-FP counter-examples to the ones you've cherry-picked.
Every single large scale problem is a distributed problem simply because human societies are multi-agent distributed systems and programming languages are human-computer interfaces.
The issues at scale are systemic and arise from the design trade-offs made when your system's requirements bumps against the limits of computation. No language/paradigm can work around those.
The best a language can do is abstract-away the complexities behind a problem - solve it once (in the language/paradigm's preferred way) and give the human an interface/concept to work with.
Okay, I got really confused by this whole mandatory thing. I never said FP should be mandatory at scale. I said it had a moderate benefit at scale. You respond with "well actually, it's not mandatory at Google-scale" so I assumed that you were trying to refute the fact that FP has benefit at scale.
You also followed this up with
> The kind of problems that emerge at scale are not the kind of problems FP tackles.
I cherry picked these examples to demonstrate that you're completely talking out of your ass here.
> I didn’t say it is impossible to do X with FP - I said it is not necessary to do X in FP. You can convince yourself of that by looking for larger-scale non-FP counter-examples to the ones you've cherry-picked.
I never said it wasn't possible to tackle these problems without FP.
You need to get rid or the assumption that "if X is better than Y at task Z, everyone will use X rather than Y for task Z". You've used that line of logic to attempt to invalidate FP's capabilities. It simply does not make sense.
