First I don't think this is the end of those languages. I still write code in Ruby almost daily, mostly to solve smaller issues; Ruby acts as the ultimate glue that connects everything here.

Having said that, Ruby is on a path to extinction. That started way before AI though and has many different reasons; it happened to perl before and now ruby is following suit. Lack of trust in RubyCentral as our divine new ruler is one (recently), after they decided to turn against the community. Soon Ruby can be renamed into Suby, to indicate Shopify running the show now. What is interesting is that you still see articles "ruby is not dead, ruby is not dead". Just the frequency of those articles coming up is worrying - it's like someone trying to pitch last minute sales - and then the company goes bankrupt. The human mind is a strange thing.

One good advantage of e. g. Python and Ruby is that they are excellent at prototyping ideas into code. That part won't go away, even if AI infiltrates more computers.

Why wouldn't they go away for prototyping? If an LLM can help you prototype in whatever language, why pick Ruby or Python?

(This isn't a gotcha question. I primarily use python these days, but I'm not married to it).
