Replacing the buttons with a tablet has always been a cost saving measure on Tesla's part that was marketed as "futuristic", physical switches and dials made of plastic and metal as well as the underlying components will never be as cheap or as easy to wire as a simple touchscreen control. Other car companies followed suit, because Tesla made a method of reducing their own manufacturing costs hip, so many of them jumped on it.

But, Tesla tablets were designed with the belief that this cost saving is possible because of the delusion that full autonomous self driving is possible with existing hardware through software updates. When self driving didn't happen after a decade of trying, people realized how inconvenient and dangerous it is that the only way to adjust the AC, stereo volume, and sideview mirrors while driving is through a tablet with no tactile feedback. So now, we are finally seeing that trend reversing.
