Does HCl still exist?

I'm curious, can you help me understand if HCl still exists? It's a chemical compound I've heard of before, but I'm not sure if it's still around or if it's been replaced by something else. I'm interested in learning more about its properties and applications, as well as any recent research or discoveries related to it. Can you provide some insights and clarify if HCl is still a relevant and active chemical compound in today's scientific community?
