There are remotes for PC. I have one right now, and they are pretty cheap in Amazon. One nice thing is that they can also do limited control of the TV (through IR, obv).
One thing to keep in mind is that most identity not all of these remotes have a gyro mouse.
It might be that they are conflating GenAI with services such as Google Assistant ot Siri. Though I personally find that Google Assistant is/was more useful that their GenAI implementation (Gemini).
