Quickly developed serverless functions combined with continuous deployment, and anyone can make edits in the entire codebase sounds like a dystopian nightmare. The amount of logging that is required to debug and find bugs is extreme.

Using Erlang to write serverless functions seems like avoiding all the huge benefits BEAM can offer.

>Additionally, product engineers predominantly write code in stateless, serverless functions in PHP, Python, and Erlang for their benefits in simplicity, productivity, and iteration speed.

>To boost developer productivity, Meta has adopted continuous deployment universally and enabled more developers to write serverless functions rather than traditional service code.
