That’s because in today’s cloud everything, shard everything, no-SQL, multi-core, scale until Google buys us world, people are starting to forget that there are still a great many real-world tasks that run just fine on a single computer, and have no reasonable prospect of needing a second CPU core, much less a second computer.

Just for one public example, the Dancer Advent calendar.  Someone recently said it typically gets less than 2000 visits monthly.  That’s about one visitor every *20 minutes* on average.  You could probably run the site from a Raspberry Pi, single-threaded, and never even know the difference from how it’s run now.
