Fire all architects!
I've read Neil Leach's opinion piece linked in the article.
Observation #1: it reads like the Prof. asked ChatGPT whether architects would become extinct under threat from AI, and believed the machine. Chuckle.
Observation #2: observation #1 is unfair. He makes a very valid, albeit not conceptually new, point that more and more technical things can and will be automated (I'd add, with or without AI, regardless of what one's definition of "intelligence" is), and the focus of the profession will have to shift. Knowing how to do the technicalities will not be enough to get hired by an architecture firm.
The last point has nothing to do with AI. The more repetitive tasks will be outsourced somewhere, probably not quite overnight. I remember watercooler talks in the renowned research division of a major company about the danger of the researchers' jobs eventually going to eminently intelligent agents with lower wages. My position was then (~20 years ago) that by the time those intelligent agents learnt what I did I would be doing something else. Looking back, I am doing something else indeed. I am not out of a job yet.
Observation #3: it is only after the pitiful humans, including architects (real or software ones), accumulate enough experience, make enough mistakes, learn from them, and generate sufficient quantity of artifacts of sufficient quality that AI could possibly hope to make the next step of learning that. I, for one, am not inclined to slide into desperation yet.
[Aside - observation #4: where I live an architect is not required to build a structure, only safety and sanitation engineers are a must. So on occasion buildings are constructed based on minor rehashing (presumably - hopefully! - by cheaper architects) of existing blueprints or whatever - no need for AI. It shows, unfortunately.]
