Important stuff. I think critical analysis of luddism, romanticism, nostalgia and general idolisation of the past should be required reading/understanding for leftists. Too many people with anprim tendencies or who's views are best summarised as "technology bad, society bad, fuck gays and the disabled if it gives me an excuse" rather than any meaningful set of beliefs.
Progressive movements should be associated with tower blocks, abundant housing, skyscrapers, dense cities, urbanism, technology and science and distribution of the benefits of it equally for all rather than the few, and people should be exposed to arguments that show why this is desirable, rather than have their disillusionment with capitalism be subverted into a hatred for modernity.
That's what solarpunk is about. Technology for the benefit of humanity, not technology against humanity not humanity against all technology yearning to delete access to information or recombine waste and drinking water all the same.
As someone who never romanticized the past or saw utopias in traditional fantasy (genre?), I could never understand why others would, even the cute versions seem awful because they have no internet, but it's always nice to hear a perspective so alien to my own.
