Beyond that the smartness is very patchy. They can do math problems beyond 99% of humans but lack the common sense understanding to take over most jobs.

Yep, the lack of commons sense is sometimes very evident.

For instance, one of these popular generative AI services refused to remove copyright watermark from an image when asked directly. Then I told it that the image has weird text artifacts on it, and asked it to remove them. That worked perfectly.

Most jobs involve complex long term tasks - which isn't something that's natural to LLMs.
