- Three different instances of "The X is Y" in a single short comment

- Relatively new account, "AI Engineer building agentic systems"

- Most past comments contain em-dashes, more "The X is Y", etc.

What triggered me to ask was because I can see myself writing that. Not the content but the style. In the old days, I will spend time finessing an argument and feel happy about it. But with the pace nowadays plus the AI, it is a different world, so do not know.
