Because it's not an argument, it's just lazily recycling language tropes.

> Rust is immature

I recuse myself due to fanboyism.

> C++ is intractable

Except to all the firms and people successfully using it.

> Python is fundamentally unusable at scale

Except to all the firms and people successfully using it.

> Curius why people downvote this.. its a perfect valid argument.

Because it's a list of opinions on languages. No specifics provided, and stated in a way that appears to be trolling (deliberate or accidental on the author's part). Comments like that are a dime a dozen in programming language threads and add nothing to the overall conversation.

I’d hazard a guess that Meta put a fair amount of effort into coming up with that list, applying business context to their specific technology problems.

Whereas the OP simply reeled off a list of half-baked subjective opinions.

The “all languages are ‘fundamentally’ bad except my favourite” argument?

It’s bad no matter what single language you’re promoting.

Where's the argument? It makes broad claims about the languages, that many people would disagree with, with no substantiation.

Four unsupported hyperbolic assertions don't make an argument.

No it's not. It's just a list of opinions without any actual arguments.

Valid but you gotta realize they do this to weed out bad developers.
