As someone who has been around long enough to actually remember setting up /cgi-bin/... there is a lot more to lambdas. They are scalable (including, importantly, down to zero!), have their own dedicated resources for each process, and are pretty efficient at being put to sleep and woken up. Plus the code is immutable by default and you get a lot out of the box like logging and setting limits. I wouldn't start a new project with CGI at all right now but I use Lambda constantly.
