What is Russell's paradox in simple terms?

It's the set of sets that don't contain themselves—does it contain itself

Type theory vs set theory: which wins?

Type theory dodges paradoxes without ZFC's axiom bloat, powering safe programming and math proofs. Sets linger for basics.

How does category theory explain types?

Types are objects, functions arrows—full category. Powers abstraction in langs like Haskell, no set crutches needed.
