> Unfortunately, the process of building houses can't be compared to building software. Houses don't get bolted sideways onto scyscrapers 5 years after they're built, or suddenly need to accommodate multiple order of magnitude more people than they were originally built to hold. These are regular occurrences in the software world.

Most likely, not a lot of things compare to building houses in all aspects.

The point is, if developers are having problems wrt. scaling, then we need to build tools that abstract away scale. Define a language that allows the runtime to auto-scale, depending on load. As far as I can see, it's "just" another engineering challenge, not essentially different from figuring out how to make a skyscraper withstand heavy winds.
