Yeah one thing I noticed while going through some of the material is how often I learned details about certain tech that I would have never had reason to come across working for big tech or startups. s3 duplication and different storage classes across multiple regions for example. I've obviously heard about and know the general concept of these things during scalability discussions and meetings and what not but there was never a technical or business reason for me to get familiar with it myself. It was always an abstract concept that was either handled in a proprietary way by another team in another building somewhere or something we only had to worry about if we 100x our user base and need to start expanding internationally after funding round xyz.
