I fear that we are moving towards a future that is shaped by monopolies (or the "digitalisation" supports monoposlistic strategies). If you read the slides, you notice that GM understands that by controlling everything (manufacturing the car, supply chain, the app) it makes more profits. I think that there is a trend in many industries towards monopolies, if you for example look at amazon or google. I don't think it's healthy and I am convinced that there is not enough awareness to tame these giants.
