> Why do people spend so much energy shooting down a language nobody uses? If you don’t like it you don’t have to use it.
Because this language isn't made by a nobody. It's made by a popular person with a following, so the language _will_ get used by a non-insignificant number of people. And those people _will_ (re)implement all the things that you want a language to have (database connections, networking libraries, (de)serialization libraries, etc.). And these things, which can be performance/security-critical, will be impacted by the issues people are pointing out.
Once we reach this plausible scenario, it's likely that some software that you want to use on, say, your server, will depend on those libraries. And _then_, like it or not, _you_ will be impacted by the choices of the language and be subject to whichever bugs all those people made when reimplementing (in this case) hash tables.
We could assume that everyone writing libraries in this language will be an expert and not make mistakes, but that is just a non-starter. In a sufficiently-large ecosystem, the people writing code will come from all sorts of backgrounds and have all levels of expertise, so you _will_ get buggy code in important libraries, and those bugs are the stuff most CVEs are made of nowadays.
I get with what you are saying that people are free to develop a language as they choose, and I agree with you there---I'm building my own and it's _not_ a modern language---but there can be consequences in the larger industry, and that's the "scary" part.
