What I'm trying to point out is the shift in complexity and similarities between the areas of the same complexity. Check this out:

- 2020s appliances (throw away manuals) are like 90s hardware toolbox (throw away manuals)

- 2020s smartphones (easy to understand manuals) are like 90s appliances (easy to understand manuals)

- 2020s specialized tools (manuals with mental models) are like 90s computers (manuals with mental models)
