Improvements: They do need to move more towards an online/in-store-equivalency platform model like Walmart, maybe with a handheld scanner self-checkout and loss-prevention AI. Heck, skip the stores entirely with delivery only-sales might be a better idea to eliminate shrinkage.
I can't see WB buying any other companies on the list besides GE or 3M because it's not clear the others are diversified, defensible, undisruptable and simple enough.
