I wish I had done this starting a decade ago. Now, with AI, it feels pointless. These powerful AI tools have slurped all of that valuable information up while simultaneously removing all value from actually posting any of it going forward.
1. You will learn more, even when you think you know everything there is to know about the topic.
2. You can point to a thing you personally created. It's nice to be discussing a technical topic and be able to say, "Hey, I actually wrote an article about that, I'll send you the link."
3. AI might slurp up some of what you write, but it's a blurry filter over information. Your unique writing, details, and perspective are your own.
Finally, it can be fun or rewarding in the same way drawing, painting, or any other creative act can be. If it's not, then channel your effort into something else.
Wait long enough and there will be situations where you did something in the past that works really well, but you can't remember anymore what you did or why you did it. An AI doesn't really help you then.
If you want recognition, then writing tech articles is a difficult path to help you gain status or become known.
My guess is that you just dislike helping the enemy. I'm often more driven for negative reasons than I am for positive ones.
Not at all. That's like saying it feels pointless to write a blog if there's search. Like gwern says, lots of people are probably going to be looking for information through LLMs in the future. If you don't write what you're thinking, you'll likely be invisible or illegible to the future. Might as well write it down.
