I think you're conflating a couple of different things here.
just have a Bluetooth radio and that’s it
and
I like to have actual buttons
These are two separate issues. The former, in my view, deals largely with what is seen as an extraneous or even potentially unwanted set of features. Especially in so much as cars are quite famously some of the worst devices people own in terms of keeping their data private and secure. Better to have a car that doesn't collect that data in the first place, and just sticks to being a car that goes vroom. Or whirrrrr, as the case may be with an EV. But there are advantages to the more advanced features too. Navigation, lane assist, adaptive cruise control, etc. Whether you want the features or not is an entirely personal decision.
But this is not the same as the question of how you interface with the car. Yes, more advanced features are probably going to require a more complicated UI, maybe including a touch screen, though centre console knobs can achieve the same.
But the core of this criticism, I think, is about whether you can keep your eyes on the road while driving. And that means that you should be able to do the core things related to driving: steer, accelerate, brake, indicate, turn on/off lights (including high beam), and adjust wiper settings all from the steering wheel. And secondary but important frequently-accessed settings like AC temperature, radio volume, radio channel/mode, and turning on/off cruise control should be doable using physical knobs and buttons, though these may be located in the centre console. The important thing here is that even if some more advanced features do exist to be interacted with via touch screen, they don't have to mean (and shouldn't mean) the important driving-critical features are only available via a dangerous touch screen.
