Nice article and explanations!

On a tangential note, I keep noticing "why x matters", "it's crucial here" that just remind me of Claude. Recently Claude has been gaslighting me in complex problems with such statements and seeing them on an article is low-key infuriating at this point. I can't trust Claude anymore on the most complex problems where it sometimes gets the answer right but completely misses the point and introduces huge complex blocks of code and logic with precisely "why it matters", "this is crucial here".
