It's a weird argument, one born from serious ignorance. He points out the industry has weathered disruptions before, failing to mention the crucial years from 2004-2022 where profits were negative (which started before the crash) for both dealers and manufacturers. Besides a reflection of shrinking real incomes, it also reflected Adam Smith's ideals, as the internet inverted the dealer/buyer dynamic, giving buyers tons of advantages.
My guess is this person only hears about auto innovations from Musk, who is very good at adding existing tech to his car and portraying it as some great advancement on his company's part alone. As someone in the industry, I can say the cell phone is a huge component of ,most cars these days, with the tech being developed and implemented as quickly as possible. People see the Android Auto/Apple Carplay ads, and don't realize most cars have already have similar features that app offers.
My guess is this person literally has no idea what they're talking about. They might as well have been high when they wrote this. When Tesla is making millions of cars without problems, let me know. Until then, its a boutique product with great marketing lucky enough to exist in an economy where the investor class is scooping up most of the money and can thus afford to pay too much to do the right thing in as showy as way as possible.
