A weed is essentially any undesired plant that self propagates effectively. The fact that some of them are beneficial in some aspect is irrelevant if they are unwanted. The entire point of a garden is that it's full of stuff that some human wants.
Clover is certainly not what concerns typical gardeners. Is there a reason I should love the morning glories that are constantly trying to kill my tomatoes?
Clover is not necessary for healthy vegetables. Also he was talking about clover in the context of lawn, not garden anyway. So this robot wouldn't even be relevant.
The whole comment seems bizarre to me. It's like some strange gardening pretension.
It's not necessary, but clover is very beneficial for all sorts of plants because it fixes nitrogren. I can't reply to some other person but yes, it's good for vegetables, too, because more nitrogen means more growth.
Had some builders in who trashed the lawn and it needed covering quickly to reduce the mud. I threw down a clover and fenscue mix and within 7 days had a full lawn that is near bullet proof, winter and summer. I'd prefer not to have clover but it's extremely drought resistant and the bees love it.
