People are downvoting you because you're writing things that are:
- factually wrong (revealing you don't know very basic info about Rust)
- anecdotal
- inflammatory (as you yourself admit when you say your comments were "crude")
It's not that people are being fanboys. I see lots of non-downvoted comments about not wanting to use Rust. Look at any HN thread about Zig, and you'll see a ton of non-grey comments that say Zig is better or that modern C/C++ don't need replacing.
If you want to sincerely debate Rust, you should learn the basics (for example, understanding how it's intended to reuse the C ecosystem, not "throw it away"); stop insulting other people in the thread (e.g. saying that using Rust is "playing with toys"); and acknowledging that it's not intended to appeal to anyone who thinks they're able to perfectly manage memory in C/C++ without any mistakes.
On that last point: no one with a lot of experience in C/C++ thinks it's possible to manage memory in those languages without dangerous bugs, and increasingly people think adopting a new language (Rust) is a good trade-off for avoiding whole classes of memory bugs.
