You need to advance a theory about how the BEAM could make a 95% improvement in a way the alternatives cannot.

For example, a Go has a very good asynchronous story as well and while it may not be exactly as good as BEAM languages, it makes up for it in straight line execution performance.

I’ve personally rewritten a few carefully optimized Python applications in pretty naive Go (without significant rearchitecting) and witnessed 50X-1000X performance improvements. And moreover Go allows for more optimization beyond what Python allows (e.g., consolidating allocations and lifting them out of the hot path).
