I'm working on a golf startup atm, so this is relevant.

These are certainly generated, as virtually every golf club has an insane and unworkable head, just like Midjourney. AI doesn't seem to focus on that level of detail.

Others look something like a soup plate attached to a stick, and it is common to see right handed players using left handed clubs.
