Rust is a tool that allows one to build cars for humans to drive, in order to avoid certain accidents. If you try to put your dog in the driver’s seat of a Rust-powered car, Rust will stop you and ask you to produce proof that the dog is a qualified human driver.
The world is a pretty big place, so of course there are people who sometimes put their dog in the driver’s seat. Sometimes by accident, sometimes out of necessity, and sometimes because they think it’s mighty fun. Since Rust is strict about who or what gets to drive the car, these people build their cars using other languages.
Some Rust-heads, however, are pretty adamant that cars are to be driven by qualified humans only, and therefore keep nagging everyone about how all cars should be built with Rust.
As a Rust programmer I'm fine with cars driven by dogs, I just want that to be clearly acknowledged as unsafe, and if that car is be driven in public roads, I would also like a safety comment stating all the precautions taken to make that safe for others, preferably reviewed by the police as well.
I for one don't care about memory safety. Rust makes it easier to compose software by expressing everything in your function/module signature. This is what OOP aimed to do, but was quite prescriptive (a datatype often isn't the natural unit of encapsulation). It maximizes local reasoning, so you can make changes to a large codebase with less understanding of uses elsewhere, and reuse functionality in new ways without changes.
C#, Go, Swift are (mostly) memory safe, but I don't think they provide this level of modularity or broader reliability. Expressive interfaces/contracts are useful for all sorts of things, you can use them for memory management but for me that's almost a by-product. I certainly don't consider it a restriction on the kinds of program you can write
before rust, if you wanted to use a "fast" programming language you had to use C or C++, which are fraught with sharp edges. Rust gives you all the performance benefits of a compiled language, with barely any sharp edges.
Using python for a purpose like this is extremely strange -- it clearly is just technology debt they've been carrying around from a silly decision over a decade ago -- so someone mentioned a contemporary, more acceptable alternative. I don't really see why this threatens some people, much less the incredibly stupid "religious" nonsense.
Rust has lots of inertia behind it, a fantastic core library, fantastic concurrency and scalability and excellent LLM support. If someone were greenfield building a service like this today, instead of being bound by poor decisions in the past, had infinite knowledge of every toolset and language and option, there is a very good chance they would settle on Rust. They might not, but it's definitely a finalist. So not remotely surprising someone would mention it.
That this caused someone to flip out is hilarious though.
This is a weird conversation. Python was a strange choice back then, but is now probably the most popular programming language in existence. If anything the choice of Python (and C++) was remarkable foresight / luck.
If Eve were green-fielded today, there is a 0% chance they would choose Python anywhere in the service layer for an online game. Zero chance.
Python is a fantastic "glue" programming language. A duct-tape language. It's awesome for little scripts, or for gluing together some AI scripts, where you're basically atomically gluing a series of calls to giant native C/C++ libraries like pytorch that are then doing a series of calls to giant native C/C++ libraries like CUDA. Where the overhead of python is negligible compared to some heavy lifting being done by a better language/system.
The simple fact that we're talking about a service that was stuck on Python 2 two decades after it was replaced, half a decade after it was fully deprecated, reveals this to be 100% just debt. The fact that they talk about millions of lines of Python code, and that Python 3 represents a big speedup for their operations, again betrays it to be nothing but debt. They have Python code in the critical flow, not just as a light glue over intensive code, and they have almost certainly spent untold dollars on extra hardware, delivering a worse experience for their users, because they had a "python enthusiast" in a critical position decades ago.
Python is very strange programming language for a MMORPG. I'd imagine they would write it in C++ or something. They don't quite explain what they use it for.
And yeah, using a faster but safe language could help immensely.
Python is just a part of the tech stack, there's also a lot of C/C++ code. How much Python vs C/C++ is hard to say from the outside though, but the parts that have been open-sourced are pretty much all C/C++:
The Jehovah's Witnesses of programming
Can someone explain to my non-programmer self what the deal is with Rust?
Even not being in the tech space, I have long picked up on this quasi-religous aura around it.

Almost three decades ago—development started in 1999 and the game was released in 2003.

That's totally ok. "It works on my machine" with no info on what that machine looks like, is much worse

Will you poor contributors ever shut up?
Very aggressive. "Will you $FAVORITE_LANG people ever shut up?"
