@dhh Wish you had given the ASUS Zephyrus G14 a chance. It's a bit heavier than the F13, but it's a joy to work on. There's nothing to dislike about the G14, except that it's a bit flashy with the LED strip on the back of the lid. It beats the F13 in every aspect.
I'd stick with Go, Rust, and Python for the rest of my life, unless something significant comes along that I can't resist changing to. Other than that, I'm pretty much well-equipped!
The software industry is rapidly converging on just three languages: Go, Rust, and JS.
It would be smart to learn one of those really well, and have at least a working acquaintance with the other two.
