A few others have mentioned that Quibi is not an interesting enough alternative timewasting app to Snapchat, Instagram, etc. I agree and I'm glad to see it fail for that reason; I want my attention span back and I'm trying to cut these things out of my life. I notice my well-being improves when I do.
That's personal preference obviously, and people are free to spend their time how they want, but I think the loss of attention span is a culture-scale problem now and excising these companies from our lives is a necessary treatment.
I hope Quibi folds permanently and we salt the earth where it stood.
