The rationale is that it's actually clearer to eager initialize. You don't need to worry about timing/concurrency that way. Lazy init is inherently more complex than eager init, so there should be a reason to choose lazy over eager rather than the other way around.

But it’s really hard to see, because our human brains struggle to think about this Clock function as something for generating discrete snapshots of a clock, instead of representing a persistent thing that changes over time.

There is interactive state as well. What about modals that come up because something is clicked? What is the active tab? Is this menu open or closed? What scroll position are they at? There are infinite permutations of this. Imagine a warning bar that shows up seven seconds after the user logs in to warn user about their expired credit card which contains a custom styled select menu which can be in an open or closed state, but only on the user settings page.

Remember the timing thing? We might think of timing as one generic form of state. There are countless other things that could be state related. Is the user logged in or not? What plan are they on? Is their credit card expired thus showing some kind of special message? Do situational things like time/date/geolocation change state? What about real-time data? Stuff from an API?

Slide 13:
“No man ever steps in the same river twice, for it's not the same river and he's not the same man.”
― Heraclitus
Of course it’s not the same river — the river, is, what? The water flowing past your feet? The sound that it makes? These things are different at every moment. Our idea of ‘the river’ doesn’t correspond to anything in the real world. Understanding this concept means getting closer to an understanding of reality itself — once you fully absorb the impact of this idea, it changes you, from a person who didn’t have that understanding into one who does.
And as you bask in your newfound zen-like enlightenment, you discover an almost spiritually calming effect — the world as it is right now is the only thing that matters, not the state of the world as it was yesterday or as it will be tomorrow.
Slide 39:
“No man ever steps in the same river twice, for it's not the same river and he's not the same man.”
― Heraclitus
And I think Heraclitus probably understood it all along. There’s a paradox contained in this statement. If the concept of identity over time is meaningless, then what do we mean by ‘it’ and ‘he’?
