The alarming rise in the incident rate of inappropriate chargebacks ("my fries were cold") really pisses me off as a sane user of contemporary credit card infrastructure. That is, I think of chargebacks as an absolute last resort; essentially a bulwark/ombudsman to protect me from bad actors. It should be used incredibly conservatively, and it should have significant reprocussions if it is used inappropriately; sort of like steep fines for hitting the emergency strip on a subway because someone wont move their backpack.
If chargebacks go away and aren't replaced by something at least as effective, that means that we're losing one of the most significant advantages intrinsic to the payment mechanism: peace of mind.
