Can say the same for ci/cd. Author talks about integration tests, setting a barebones "build this and deploy it" pipeline is far more trivial and skips having to do it manually every time.
Meanwhile, my experience is a minimal CICD pipeline takes half an hour once you know manual deployment, and I lose far more having to SSH and run scripts myself than telling a machine to do it for me (not just time but mental satisfaction too).
Though I wouldn't call either fancy in this year. Only past that stage, where the benefits drop sharply for individuals.
