It's probably easier to find an employer that's already convinced. But that's not easy either. :P I'm working in Rust now, because that's what the employer wants to do and it works enough. Half of my work problems would evaporate if we switched to BEAM, but I'd still have the other half and new ones and I'm not sure the rest of the team would be as excited as I am. And they almost certainly wouldn't let me hot load code, which means less fun and less fast iteration :(

Convincing an employer to switch languages is generally hard, regardless of which language, but switching to a system built on BEAM is probably a bigger change than most.
