There's no need to be this harsh. We should always celebrate people making things even if they don't benefit us directly, to me that's even the essence of hacking
Sure, making is good and all, but if you want people to care you should put in effort to make them care. Toy programming languages is a very crowded space.
Sorry, how is it a 'crowded space'? Languages aren't startups, they don't have to compete on a market to be viable (unless they're proprietary of course). As long as someone somewhere has an interest in it, it will live on.
A language needs an active community of many users. In these days, without support for libraries that make software exciting and useful a language can definitely die as a platform. Those are some of the many qualities that persuade users to invest time into learning a new language. Otherwise, they'll go with something already established.
So I disagree, there is definitely competition amongst programming languages.
That is not dead which may eternal lie, and in strange aeons even death may die. Remember that weird language that looked like Java and was used by nobody except script kiddies until the Web exploded? Or that quirky little language with forced indentation that was overshadowed by Perl and Matlab well into the 90s and the 00s? Open source projects don't have the same constraints as commercial ones, they can remain dormant or unnoticed for years before suddenly taking off.
