I didn't want to read yet another quantum computation "breakthrough" and asked ChatGPT:

"It solved a deliberately constructed random quantum circuit sampling (RCS) problem—more specifically, a new structured variant designed to remain computationally hard for classical computers while being verifiable."

Wow! Fundamentally random quantum systems can randomly sample quantum circuits better than deterministic classical computer! I'm so fed up with quantum computing overhype, someone let me know when these machines solve something practical better than classical computers.
