I dunno man.
Kinda feel like the true Techno-Optimists were the people collectively hacking together solutions under open source principles, and that quite a lot of the libertarian-eque mumbo-jumbo here invisibly stands on the shoulders of those giants.
The free market is arguably more aligned to a product that allows a monkey direct access to its dopamine center than one that lets a monkey rule the stars.
While I agree that technology growth is one of the most important metrics for the future health of a society, the idea that optimal growth necessitates uncontrolled markets or a whole host of the other things piggybacking on that core here is a bit silly.
A more narrowly scoped manifesto that was essentially just "tech accelerates beneficial progress; there's an opportunity cost to delaying tech" would likely have had better legs than an umbrella of rhetoric that tries to cover all bases and as such alienates everyone other than the author and the sycophants in their circle.
It's frustrating, as I agree with a lot of the broad sentiment and have been extremely disappointed in the tech pessimism I've been seeing grow dramatically over the past few months and years - but I really don't feel this manifesto speaks for nor to me, as optimistic about tech as I might be.
