I appreciate the frustration and I am right there with you as a user.
However, it is actually hard (and costly) to manufacture and quality control physical switches that will survive the life time of a warranty + a few years (in terms of mechanical failure, dirt, corrosion, water ingress, etc.). Once you appreciate this then it is pretty easy to see how the design choices of using capacitive interfaces are a no brainer for consumer electronics and appliances.
On top of it you have the marketing push of capacitive interfaces = modern.
