> Chat is like the command line

Exactly. Nobody really wants to use the command-line as the primary mode of computing; even the experts who know how to use it well. People will accept it when there is no better tool for the job, but it is not going to become the preferred way to use computers again no matter how much easier it is to use this time. We didn't move away from the command-line simply because it required some specialized knowledge to use.

Chatting with LLMs looks pretty good right now because we haven't yet figured out a better way, but there is no reason to think we won't figure out a better way. Almost certainly people will revert to chat for certain tasks, like people still use the command-line even today, but it won't be the primary mode of computing like the current crop of services are betting on. This technology is much too valuable for it to stay locked in shitty chat clients (and especially shitty chat clients serving advertisements, which is the inevitable future for these businesses betting on chat — they can't keep haemorrhaging money forever and individuals won't pay enough for a software service).
