I’ve found that with most libraries - they always provide toy foobar style examples assuming it’ll make them approachable, but in reality, instead makes it impossible to understand the practical way to use it in real world settings.

That is quite of an hard problem to solve.

Solutions like effect are easier to appreciate as your application starts growing in complexity beyond simple todo apps.

Solutions like effect/schema are easier to appreciate as soon as you start needing complex types, encoding/decoding, branded types and more.

I am quite confident that effect will keep growing in popularity steadily and eventually grow.

It took more than 5/6 years for TypeScript or React to start getting spread around the JS community. Effect is here to stay and I'm confident it will eventually be adopted by plenty of developers.

Reminds me of Animal / Cat / Dog examples.

For the love of god just use User / RegisteredUser / GuestUser and other abstractions that have some basis in the real world.
