It's similar in intention, but "serverless is just `cgi-bin`" misses a lot of nuance. Zerg and cgi-bin are solving different problems and with different implementations. It's extremely difficult, if not impossible in some environments, to get the same kind of isolation with cgi-bin that you do out of a VM.

You gain on isolation with Zerg (and other "VM per request" things) but you lose on everything else compared to CGI with processes.

But you can reach comparable levels of isolation with processes: just use Linux namespaces.
