Ask HN: What Happened to Coding Competions?

I hadn't thought about these in a while, but what happened to Topcoder, Code Jam, etc.? I did some quick research and saw that those two shut down in 2023, but there wasn't much explanation as to why. I thought of this because people keep talking about how productive they are with LLM coding tools, and I thought it would be fun to put the people proclaiming this (along with their LLM tools) up against people not using LLMs in a topcoder competition. Turns out, those competitions don't exist anymore and I'm sad.
