It gives the human an advantage; humans get confused easily when things
keep moving around. So go is easier than chess for humans. Maybe current
chess programs and current go programs are equally strong but we just don't
realize it ;-).

Yes. But it's difficult.

At the stone level, nothing changes, except the last stone played (and
captures).

At the chain liberty level, all the chains adjacent to the last stone
played change, but the rest of the board is unaffected.

At the tactical reading level, a few groups nearby might change, or they
might not. The tactical status of a group on the other side of the board
might change if the move is a ladder breaker.

At the group strength level, it gets more complex.
