Once Jonathan Blow's Jai comes out next year, the language that inspired conception of both of these, Odin will likely have no chance competing on the marketing side of things with programmers and will be taken over by Jai, and Zig in a large extent as well. So the future of the language might not be as solid as it might seem and it might end up just as an internal tool for JangaFX, which is how it originated.
Having the "web stuff" can attract literally millions of developers whom can elevate the language into more stable and broadly used language. More documentation would become available, libraries, youtube videos, internet presence in general.
I haven’t heard this before. Do you have a source on this?
Here is a list with his videos where he goes from conception to something tangible: https://www.youtube.com/watch?v=TH9VCN6UkyQ&list=PLmV5I2fxai...
The first video is from September 17, 2014.
Zig's first commit was Aug 5, 2015.
Odin has first commit in Jul 7, 2016.
He also stated recently that he doesn't care too much about language design at a syntax level, or better said it's not his top focus as the overarching concepts are more important to him.
I think there is a chance that people may have a hard time to adopt to the language. His strong focus on gamedev will further cut down the audience. It will certainly draw a lot of attention but a massive adoption is highly questionable.
