Is it crazy that I only found out Chatgpt existed in 2025?

I didnt even know the concept of Ai/Chatgpt existed until last year when my friends kept using it to write emails for them. It was insane I went down this whole rabbit hole and now i dont use chat gpt at all. It was a very short lived fascination but I definitely want to check in on the advancements in the future because the concept of this is actually mind blowing. I always wondered what the “big thing” of this decade would be but I couldnt have imagined it being Ai lol.
