this is not doomer view, are you understand that there are entire generation of people that don't use browser at all????
they use only smartphone in their life and mobile apps for everything, Yes they use social media like tiktok,instagram etc never bother to use "open web" that live in browser
You can disagree but there are tons of people live in this walled garden
I use the 'open Web' on my phone and basically no apps (I side-load some for testing): I don't even have a sign-in for the apps store. And we had worse walled gardens before - I created an early ISP in the UK to help get people over the walls then. So it's all still there if they want it. And my tenn children use it - so which generation did you have in mind?
