Absolutely "not necessarily". SWE requires an extensive amount of learning (if you're lucky :)).
Unless one has extraordinary mnemonic capabilities, note taking is a way to structure and store concepts.
Even if this wasn't the case, personal notes are still a more efficient/effective way than googling, for two reasons: 1. on the notes, one puts the processed version of a concept, so that it's safer/more stable/improved/cleaner/adapted etc. 2. personal notes follow the mind of who writes them, so the concepts are faster to find.
