But still, let's face reality. Rails with Ruby and Django with python's biggest advantage was readability and accessibility. For many, it is just much nicer reading Ruby code than Rust code. But LLMs have completely changed the equation, and development with a statically typed language plays much better into the agentic feedback loop. Add the memory safety guarantees of the rust compiler and the incredible runtime speed even compared to the Java Stack you will see many benefits.
I am biased since I love Rust, but I think backend technologies are going to move more towards statically typed memory safe languages.
Also if you use an agent to write most of your code, with python it gives me a lot of stomach pain just thinking about error potentials and hallucinations, with Rust, that fades to only security implications
Mostly the reasons are not of technical, but of political nature. I mean no one likes to be told that their language is "not good enough". Or "not safe enough". It is our instinct to defend what we love and have put so much time and effort into. But reality is, that Rust really helps eliminate whole classes of errors, that can happen even to the most experienced C or C++ devs.
Accepting that things will and should be rewritten in Rust - until an even better language comes along - is necessary. That does not mean that Rust needs to replace all code on earth. For sure there are many cases where it should not. But in the times of Fable and GPT 5.6, it becomes even more important to reduce any attack surface as much as possible.
But to their credit, I was very sceptical about the statements that "90% of the code will soon be written by AI" and even though we might not be at that point, I am surprised how far LLMs have gotten and how useful they have become. I can hardly image developing software the "old" way where I actually write my code by hand, like I used back in the day. The frontier models have become so powerful that I find myself in moments of surprise, where the LLM actually thought of edge cases that I would have missed
I think the GIL provides python with a great guarantee, I would probably prefer single-thread performance improvements over multithreading in python to be honest.
Anyway if I need performance, Python would probably not be my first choice
