They are probably referring to the much larger driver facing curved touchscreens for carplay/android auto that merges with the screen used for the instrument gauge. Also, the driver assist tech on the newer kia/hyundais is very good, especially for highway traffic, needing very little driver intervention.
Not the original commenter, but I would say that Toyota has a long history of being a few generations behind on tech, and also has a history of hard grey plastic interiors.
I had a 2001 Tundra. When I looked at a new Tundra in 2016 it was basically the same interior with the same knobs and controls as my 2001. I ended up with a Ford F150 instead. I think they made changes to the 2017 Tundra interior. Toyota just sticks with what works once they iron out the bugs. Other car manufacturers go for the bling to get people to buy.
