There is no alternative for Discord for bigger groups.
If there was, I still couldn’t move multiple social circles to it, no matter how much I evangelised.
The “just don’t use the less morally aligned platform” argument has always been valid only for those without a strong need for it, whether it’s X or Discord.
While they may not have been very successful, they did have a place.
At its simplest, the point is that much of programming language design is done with a masculine perspective that values technical excellence and very little feminine perspective that focuses more on social impact. Most, including myself, have a knee-jerk reaction to dismiss this argument since at first glance it appears to trade off something known useful for something that's usually little else than a buzzword, but upon further reflection the argument is sensible.
The theme of forsaking technological perfectionism in favor of reaching whatever end goal you have set is widely circulated on this forum and generally agreed with. Those of us that work as software engineers know that impact of your work is always valued more than the implementation or technical details. It's thus reasonable that when building programming languages, the needs and experience of the users should be considered. Not override everything else, but be factored into the equation.
I know if I were to write a programming language I'd probably focus on pushing the boundaries of what's technologically possible, because I find it fun and interesting. But I would have to agree that even if I did succeed in doing so, the actual impact of my work would probably be lower than that of Hedy - the author's language. Hedy is not novel technologically, but the fact that it makes it meaningfully easier to learn programming for significant numbers of people is real, undeniable impact.
Lastly, I want to note that the author's argument for underrepresentation of women in PL cannot be reduced to "those nasty men are keeping us out". Humans are tribal and any group of humans is bound to form complex social structures. Those are going to affect different people in different ways, linked paper investigates the effect on those structures on specifically women because the topic is close to the author. Whether you care about low numbers of women in PL design or not, the dynamics that have led to that being the case are worth investigating and are quite interesting on their own.
The author must consider the audience is either stupid or childish. An intelligent adult deserves respect and should not be talked about in this way, implying that they are emotionally unequipped to handle a straightforward computer error message.
Of course it does not matter for "a straightforward computer error message", in cases where the error is a simple type mismatch or a missed semicolon, but if those were the majority of the problems we encounter as programmers, our work would be trivial.
It's not difficult to imagine a situation where structuring a compiler in such a way that it keeps more state and perhaps has to perform more analysis is worthwhile, since a more useful error message saves the user time in understanding and fixing a problem.
An example that comes to mind is when in Rust I tried to create a dynamically dispatched trait, where the trait in question contained a function an argument of which was generic over a different, statically dispatched trait. Since the compiler did not know at compile time the exact object which would be instantiated, it was incapable of inferring the exact type of the second, statically dispatched trait at compile time, thus failing to compile.
The error was presented to me in a clear way that pointed out the problematic relationship between dispatch types of the two traits allowing me to understand and fix the problem quickly. If the error message was far simpler, such as "can't dynamically dispatch trait", I would have figured that out too, but it would have simply taken more valuable time. Most importantly, having to track down the issue from a minimal error message, would not have been an honorable test of my intelligence and emotional maturity, it simply would have been inefficient.
