You can in C/C++. Though, the point is that erlang has a strategy how to clean and recover from such error (some data can be lost, rarely we can crash the whole system for some errors).

I mean, you can write erlang-way in almost any language, just in this case you need to adopt all the libraries to follow the same principles.

Some languages implement similar error handling strategy by just creating a separate process per request (hello, php). We know how to clean after a worker dies (just let the worker die). Just in that case supervisor strategy is very simple.
