Is Cardano alive?

I'm just curious, is Cardano still alive? I've heard about his groundbreaking work in cryptography and blockchain technology, but I'm not sure if he's still actively involved in the cryptocurrency scene. I mean, with all the advancements and innovations happening in this field, it's hard to keep track of everyone's contributions. Could you possibly clarify this for me? I'd really appreciate it if you could provide some insight into Cardano's current status in the world of cryptocurrency and finance.
