I am 100% liseuseified, no paper books at all now

In fact, I've gone from paper book collector to loathing the damn things. They're so old fashioned and ridiculous for delivering information in the digital age. I'd say we'll still have some die hard collectors around in 2020, but paper books won't be anything but an antique toy or decoration beyond that.
Then again, I did think ePub would win the format war and that's looking doubtful now. So take my predictions with a grain of salt.
