"You most likely can't utilize the workstation 24/7. Your work hours will be concentrated into 6-10 hours per day."

I have agents running 24/7 doing research, in fact I would argue this how they will be used for most programming tasks in the near future. For chatting, I agree local inference makes no sense. But for tasks that run continually, I'm not so sure. Personal computers took a while, local inference will too, but I think it will happen.
