A lot of answers are now out of date.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Many have notes that they are out of date in sub-comments.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.
