I think calling design deliverables 'artifacts' is a misnomer.
A 10 page document that nobody will ever read is not some artifact. The only reason it would be called that is because in 200 years someone will put it in a museum to ask why the previous generations were wasting so much time.
Especially because I see so many folks talking about using AI to generate 10x more 'artifacts', and arguing that therefore they are 10x more productive.
10x of documents nobody reads it's 10 x 0 = 0
