I am not at all idealist. I am pragmatist to the core. Data is the new petrol. And exactly as in the petrol starting times, there are "entrepreneurs" and others who have no idea about value of personal data. Moving forward everyone will have this idea, and will not share freely like in this moment. People don't care, "Because they have nothing to hide", wait and see what they will do when realize how someone is profiting over this big time. People are stupid until they are not. Second point: Security. All our software is big security risk. We don't have a single os created with memory safe language in mind. In the future everything will be hackable and exploitable. You can check what is going on in Apple camp, today. Not tomorrow. There are powers in the corporate world who don't want to see this as a problem, they care about marketing, sales and profit. All of this will crumble to the ground. In near future treats will be bigger, that's why your idea is "optimistic" and mine is realistic. On human centered design....I am not interested to argue at all.
