I've been actively toying with Odin in past few days. As a Gopher, the syntax is partially familiar. But as it is a lower level language wiht manual-ish memory management, simple things require much more code to write and a ton of typecasting. Lack of any kind of OOP-ism, like inheritance(bad), encapsulation(ok), or methods(nobrainer), is very spartan and unpleasant in 2025, but that's just a personal preference. I don't think I ever used fully procedural language in my entire life. It requires a complete rewiring on one's brain. Which I'd say is a huge obstacle for most programmers, definitely from the younger crowd. For low-level guys, this is quite a nice and powerful tool. For everyone else, it's a bit of a head ache(even Zig has methods and interfaces). The language still lacks basic things like SQL drivers, solid HTTPS stack, websockets, and essentially anything related to web and networking(which has the bare bones functionality). As a Gopher, I am biased, but the web rules the world, so it is objective complaint. In the end, this is a solid language with great support for 2D and 3D graphics and advanced mathematics, which naturally makes it a very niche language for making games or anything to do with visual programming. Definitely try it out.

PS: I just read a funny comment on YT video: "Odin feels like a DSL for writing games masquerading as a systems language."
