After posting and now, reading the last post, I have come to the conclusion that, while GPT 5.6 Luna did a good job of writing it using my perspective, my voice, it still didn't feel right. Maybe because it's my first attempt at creating a digital twin, after all. All I asked was for ChatGPT to read 5 blog posts and recreate "me" based on vague notions of a digital twin. Maybe because it used some words that I have never used in any of my blog posts before. Or its robotic, sometimes LinkedIn-like speech it made.
But by trying it out, I understand just a bit of how digital twin works. However, I love writing too much to let an AI agent do my blogging. It's how I learn and conceptualize things, after all.
