Sorry, this is a strawman response. I was pretty clear about my concern for unfortunate unintended consequences; nobody is saying that there's a Silicon Valley conspiracy in action! Incidentally, I agree with your points on the benefits of social media. And it's awesome that we have so much engaging content today, but please explain if it's really OK for kids to get hooked on YouTube etc five hours a day. The solution is not to ban or demonise, but how we can educate people to have more control in their use of technology. Even Nir Eyal recognises this and implements tech restrictions in his own household. It's like gambling - sure we have self control, but let's be honest, gambling companies work very hard to make it addictive (I specifically used the term "psychologically hacked" earlier). That's a natural response to be expected from companies, user engagement is tied to company health/profitability/etc so it makes sense to maximise it as much as possible. But earlier when I called for a new design philosophy, I am hoping that tech companies can be better than that. Because you are right, nearly all of them start with a genuine belief that their tool can help people, or at the very least, it's cool and yo let's spread the word. The tools still work, like Facebook still functions as a platform to connect relatives and old classmates, but it has also become so much more than that: it's a news platform, it's a media engine, it's a publisher, it's an ad-clicking farm and so on. The tools have evolved into systems, which other forces (commercial companies, political groups etc) have learnt to leverage for their own benefit. They have become complex and life-evading enough that they can't be called neutral anymore, despite the company's best intentions. And I'll go as far as to say that these companies have some accountability. As a daily Instagram user, I do take offence with your comment regarding Instagram and girls - you are caricaturing a lot. It's not just high-fiving about body confidence and taking random selfies...
