It’s different, unfortunately. I wish you were right. The problem is that creating interesting and fun CTF challenges is a very active, time consuming, creativity-heavy task. A chess board is always the same, and always will be, but every CTF competition is unique. There is little to no incentive anymore to spend time creating the challenges. You might say “well create the challenges and share them with people who care and who want to play honestly” which is probably the right answer here, and might happen at a smaller scale. I picture CTF in the future almost like a tabletop RPG experience, one where a small amount of people will share with close friends who they trust. But the usual “open” CTF scene (as mentioned by op) is probably over for good, if we’re being honest.
