As much as i think that most of what Lewis says is drivvle, he's right.
Jackie Stewart, in particular, is a clown. It's sad, because someone like my father still hangs on his every word and regurgitates his out of touch comments verbatim. The cars are nothing like what Jackie drove, the circus itself has changed out of all recognition since he was king of the castle. He needs to let it go a bit. He has his place, but his incessant 'being available for comment' is rather tragic.
You can add Moss, Lauda, Jones & Scheckter to that list.
I don't really understand why we shouldn't listen to them and still find it interesting to discuss anything here. They may be on the older side but most have been present in the sport in some way or another for a long time. Walking around the paddock, spealking to numerous people deeply involved in the sport today.
They might be wrong at times and utter comments that does not agree with everyone, arguably so are most posters here.
