I don't think there's a viable alternative to PHP. The nerds here, hate it (and they aren't really wrong). I hate it, but it is undisputed God Emperor of Cheap Hosting. There's nothing that even comes close, for simplicity, speed, robustness, cost, and ubiquity. There are millions of pages of support, years of support forums, and hundreds of thousands of people that can work with PHP at an expert level. Despite the hate, PHP is a mature, modern language, still very much under development, and supported by many corporations. Much of the primitive stuff it started with, has been replaced (I think, rather clumsily, but it works).
The simplest hosting solutions have LAMP ("P" being "PHP"), and there are millions of LAMP servers out there. Every single one can run WP, simply by uploading a few files, creating a MySQL DB/User, tweaking a config, and Björn Stronginthearm's your uncle. Or, with things like WPE, you can click on a button in your control panel dashboard.
Also, non-HN-readers can manage just about every aspect of a WP server, once it's set up. People have made careers from that.
This sucks.
I run a couple of sites. I use WP, because it means that I don't have to waste much time, managing them. I could definitely switch over to a static generator (what I would use, if I didn't do WP), or even write my own sites, using handcoded HTML (I have done that, and have even written my own CMSes, in The Dark Ages). I just don't want to have to do that. The moment I walk away from WP, I am sealing my own fate. It will make it ten times as hard to push the sites over to someone else to manage.
I am an indifferent (at best) Web designer. Almost every person here, could probably code circles around me. That means that working on Web sites is painful and slow, detracting from what I'm actually good at.
This sucks.
