In the first section of the letter, "Why are we fighting and opposing you?", he describes atrocities committed by the United States and its allies. I think that part is what people reference as "astute points."
You don't have to love a person to understand or consider their ideas. Ted Kaczynski is a good example of an American intellectual with many philosophically worthy ideas, even if you find his methods horrific.
I omitted the reasonable points from Bin Laden's letter to focus on those that show what a wingnut he was.
Whether you agree or not doesn't matter, neither if the proposition has been debunked.
I read a bit of his manifesto once. You have to be very generously looking for the worthy ideas.
It's relevant today more than ever:
> [It argues] that the Industrial Revolution began a harmful process of natural destruction brought about by technology. Furthermore it states that forcing humans to adapt to machinery creates a sociopolitical order that suppresses human potential and freedom. [...] The manifesto states that the public largely accepts individual technological advancements as purely positive without accounting for their overall effect, including the erosion of local and individual freedom and autonomy.
Would you mind spelling them out? Because all I find hovers between old fashioned reactionism and bat shit craziness. What is the philosophical value in that?
From the Wikipedia page for Industrial Society and Its Future:
> [He argues] that the Industrial Revolution began a harmful process of natural destruction brought about by technology. Furthermore it states that forcing humans to adapt to machinery creates a sociopolitical order that suppresses human potential and freedom. [...] The manifesto states that the public largely accepts individual technological advancements as purely positive without accounting for their overall effect, including the erosion of local and individual freedom and autonomy.
This leads to some interesting questions. Do human beings still have autonomy if we allow our decisionmaking to be offloaded to machines? Is technological progress for the sake of progress a good thing? Does it serve humanity? If it does serve humanity, who does it serve and at what cost? What does our society become when human beings no longer have purpose?
Independently, Bill Joy quoted Kaczynski in a Wired article in 2000, arguing that unregulated technology can lead us down a dystopian path: https://en.wikipedia.org/wiki/Why_the_Future_Doesn%27t_Need_...
