> This is true for any company at scale. FP can be used at the fringe or the edge, but the core part demands efficiency.
I think things like real-time graphics are the exception not the rule. Most of the software run by users these days is in the context of a browser, which is implemented many layers of abstraction away from the machine. Much of the code running servers is also still interpreted scripting languages.
Don't get me wrong, I wish a lot more software was implemented with performance in mind, because the average-case user experience for software could be so much better, but a ton of the software we use today could be replaced by FP and perform just as well or better.
