#catseffect
Look at this handsome cat
His name is Grunt. He was named after the biggest, goodest orange baby, Grunt from Mass Effect. The thing is... Of the four kittens, he is the least Grunt-like. He's a chicken and a foot licker.

I dislike the `*>` and `>>` operators from #CatsEffect, because it introduces too many ways of doing things, and because it … doesn't look good for multi-line expressions. Abused by devs and LLMs alike.

Similar feelings for `fold` on Either/Option.

On #Scala's #CatsEffect library — one common myth is that it's a library built for “tagless final” (TF).

While it's true that it gives you unparalleled ability to use TF and monad transformer stacks, it's perfectly usable without. Most libraries from #Typelevel are.

Monadic effect systems (IO) are great, but they'll never be the (de jure) standard, as #Scala has Java's evaluation model and calling conventions.

The current standard for APIs doing I/O is `Future`. I'd rather have blocking I/O; easier to integrate w/ #CatsEffect, too.
