> What if you want to make two languages cooperate? If they both have their own GC, then you can't garbage collect across language boundaries, which can be annoying. I think this is similar to the microservices debate, where you have either one big transactional database or a bunch of disconnected ones where committing a transaction involving multiple services becomes increasingly difficult. This is an interesting observation. I think in both cases the ideal of having one large system remains elusive and the more robust, practical solution is RPC (basically more, smaller control loops rather than a single larger control loop). To abstract this out even further, I've noticed that this seems to be a common pattern in reliable distributed systems are architected--from Erlang's OTP to Kubernetes' controller approach. I'm actually really surprised this "controller" or "control system" architecture vs monolith architecture isn't discussed more frequently, at least in terms of reliability tradeoffs.
