A lot of answers are now out of date. Some dangerously so. And its not just 'fast moving' languages. Bash, nginx, docker, gcp, bluetooth. Much of the landscape of these tools has changed since say 2015, but that is where most of the 'core' answers are from.

Many have notes that they are out of date in sub-comments. But its hard to be noticed against a 700 upvote selected top answer.

Perhaps SO should include version numbers so that you could search for solutions to problems with specific versions or the latest as the case may be.

Out of date answers are useful when you need to fix something based on old / un-updated OS and/or software. Not every installation uses the latest versions of everything.

Having a switch that shows answers to specific versions would be a huge help. Even if those were general guesses, or if it was up to the answerer to self-report.

They've introduced "Trending (recent votes count more)" sort option recently, but it's not the default (yet?)

This isn’t a good fix, because it requires people to give enough of a shit (fight against the feeling of decay) to look through the existing answers or write new ones that won’t get many votes because the question is already answered, and I say this as someone who has am answer just like this, python added a feature in the years after the original question was answered and my answer is by far the most ergonomic and simple answer, but I have zero expectations that it will eventually be vindicated… this one question alone serves as my guidepost, SO has been in decline for years, and it’s accelerating, and they have finally noticed and are trying to fix it, but it won’t work…
