I’ve seen this a lot. The biggest reason for failure is people assume they already know everything about the VM and language. Erlang + BEAM are the most integrated pair of VM and language I know of. It’s the only VM that will preempt running processes. It’s also truly functional. A lot of really brilliant folks have written truly shit Elixir code because they underestimated the challenge. Oh you’re passing that blob to four different gen servers? Cool expect you blew out your memory copying terms between them. It’s also operationally complex and doesn’t like the normal way of doing things because quite frankly it’ll do it better. Take metrics or logging, both will slow down your application in Elixir/Erlang/BEAM by a not insignificant amount but people just shovel as much as they can into their apps assuming truths from other languages still hold. When your request times are measured in microseconds, that instrumentation is gonna slow you down. People literally buried boxes with erlang on them in the ground and they’ve worked for 20 years. Maybe give sampling a shot if it worked for a telecom maybe it’ll work for your blog :p I’ll stop rambling here. While I truly love elixir it’s a lot more of a rodeo than people expect and it extremely subtle ways. It’s also extremely expensive to hire developers. Because you’re not going to be able to hire juniors. They just don’t exist for a language like Elixir.
