It’s not far-fetched, infinite growth and all.
Since Kobo e-readers have public library integration where I live and I no longer have an Amazon account, the Kindle I bought is just sitting there. If it pans out into a subscription model and Amazon also cans other forms of side-loading, honestly Kobo + physical books would be my only go-tos: why pay extra to borrow from Amazon when my taxes already go to a library system from which I can also borrow books? I’ve transferred the books I had on the Kindle. Maybe it can be reused with a pi should it come to.
Anecdotal, but I can see this. Last year, I took a 2-3 months off of what I now call recreational internet use (e.g. keeping up with the news, forums, etc.), because my mental health and cognitive abilities have deteriorated a lot. The result wasn’t just improved mood but also regaining cognitive skills that I thought I had lost forever. Brain fog also lessened. A year later now, and the improvements are stable and still there, even though I do use the internet recreationally again. It’s still not where I used to be before, but it’s a work-in-progress anyway.
