I'm not sure if you're being sarcastic or not? Wells and septic tanks don't really scale if you have a lot of people living in an area. If too many people dig wells in the same neighborhood, the water table goes dry. Not to mention the need for everyone to buy and operate their own individual water softeners, water filters, and pumps. Septic tanks can leach into the ground (and probably into the aforementioned wells) or clog unless they're properly maintained at all times, by every neighbor. And someone needs to come by every single house and manually empty out the septic tank periodically.

So yes... I guess it is a pretty good analogy for C++. Hundreds of stinky septic tanks, right near hundreds of wells, along with a guy arguing indoor plumbing is overrated. And a buggy, informally specified reimplementation of half of Common Lisp ;)
