Pretty much exactly what I expected. You can replace Google with any other "old school" big tech company (Apple, Microsoft, Amazon) and Twitter with everything that came after it (Uber, Airbnb, Pinterest, Slack and every other successful or failed startup in the last two decades) and the comparison would look the exact same.
Apple and Netflix do not engineer their tooling in house. Googe and Fb do to a large extent and Amazon is somewhere inbetween. So no, not exactly the same
