It's all well and good saying he was wrong but the principles he outlines have been largely vindicated by the market.

Many things worked fine 30 years ago and yet have been immeasurably improved since - it's a tempting argument to not fix that which isn't broken, but ultimately a weak one. Also, there is little point in comparing computers, phones and car interiors. Incorporating physical buttons on phones involves a significant trade-off that is not an issue with computers. Car interiors are a different matter entirely. A more appropriate comparison might be conventional TV remotes vs the Apple TV remote. I've found the latter to be much more user friendly and intuitive.
