I just finished this, yes it took me a month.
I found his literary style, very compelling, it was a fun read.
I found his predictions while interesting, not very clairvoyant. BeOS is sadly no longer with us.
I did like his tie-in to the Church of the simulation at the end, though this predates the official organization of such an church.
I think it was a thought-provoking essay, I disagreed with some aspects of this predictions, especially around what a monopoly is. It's thought-provoking. It's a good read. It is not gospel
He did talk about hacker culture, and anybody being able to fix anything, but was not able to make the connection between BeOS and proprietary license and Linux with an open license. The death of BOS followed one year from the creation of this essay
