> anyone serious about designing for AI should consider non-copilot form factors that more directly extend the human mind.

Aren't auto-completes doing exactly this? It's not a co-pilot in the sense of a virtual human, but already more in the direction of a HUD.

Sure you can converse with LLMs but you can also clearly just send orders and they eagerly follow and auto-complete.

I think what the author might be trying to express in a quirky fashion, is that AI should work alongside us, looking in the same direction as we are, and not being opposite to us at the table, staring at each other's and arguing. We'll have true AI when they'll be doing our bidding, without any interaction from us.
