For anyone reading through the article or watching the YouTube video: The reddit post quoted towards the end is actually a cloaked advertisement for "coderabbit".
I didn't notice until someone in the reddit comments pointed it out, when it became obvious.
Not that it changes anything about what the article conveys, but just as a note to give context to that reddit post and what the motiviation behind writing it was.
Comparing Claude to a personal trainer is not an adequate comparison.
The personal trainer doesn't train for you, he or she teaches you movement patterns and educates you on proper form and maybe also on healthy dietary choices.
It's more like if he was paying for a personal coding tutor, which Claude or ChatGPT can theoretically be as well, but that doesn't seem to be what he did here.
