Do note that many things mentioned just happen to be incentivized or default in the BEAM, but are not required at all. Your processes don't have to crash if you don't want to let them crash, exception handling is there. Messages don't have to be 0-or-1, Manifold exists. You are absolutely not forced to use some language, you have NIFs, dirty NIFs, ports, rustler, zigler, pythonx, etc, many offering impeccable ergonomics. Some things may not be as optimized as alternatives are? Sure, but the BEAM works for Whatsapp and Discord and of all things they just use raw ETS for their most important data structure. You almost surely don't need something "better".
