It's not 2018 and Linux still has issues with this, rather it's 2018 and Linux is starting to have real issues with this.

Windows is the only desktop OS where 32-bit is still commonly used. On Linux, you nowadays generally don't have any 32-bit applications installed. Many Linux distributions don't offer 32-bit support anymore at all, because you'll have a seriously hard time finding hardware that doesn't support 64-bit.

With Steam however at the moment still only being available as 32-bit, you need 32-bit versions of the libraries that Steam uses. Distributions not hosting 32-bit libraries anymore, means you need to get these libraries in a different way.

Many distributions now actually offer you to install a Steam installer, which then gets the necessary 32-bit libraries from elsewhere.

You can also install Steam through a new package format, called "Flatpak", which includes all the necessary libraries directly in the package.

But these are all new workarounds and may still have problems. Flatpak in fact has only turned 1.0 a few days ago.

Which are those distributions? It's true that most don't offer regular applications, but at least for my distro (Arch), there is still a 32-bit repo for 64-bit systems, with various system libraries and applications that are only available as 32-bit (besides Steam, this includes Wine and various emulators for old consoles): https://www.archlinux.org/packages/?repo=Multilib

I was thinking of openSUSE and Ubuntu, but you're right that openSUSE still has 32-bit libraries around.

In the openSUSE Leap 15.0 standard repos, there's 6554 packages named "lib..." and 1368 named "lib...32bit", so roughly 20% of libraries have a 32 bit version still, which obviously could well be enough to contain all the libraries needed for Steam. (In total, there's 36237 packages, of which 1804 are 32 bit.)

With Ubuntu, I'm not entirely sure, as I don't run it, I've just heard that Lubuntu is having problems, because they would still like to support 32-bit, but with other Ubuntu flavors not anymore being released with 32-bit support, they're having trouble keeping it up. Might just be proper testing of the 32-bit libraries, though.

Well, and then there is obviously more niche distributions, which never bothered with 32-bit. Chakra Linux, for example, is so niche, they don't even provide any GTK applications in their main repository, and I think no 32-bit packages either. They do have a community repository, which has more stuff in it, but even there, I can only find around 20 packages with 32-bit support.
