Will Starlink ever be affordable for people living in least developed counties?
€600 for an entire village/favela/whatever else to have some form of internet sounds fairly reasonable in the early 21st century. And prices will surely go down over the next few years.
That said, given the base station is currently sold below cost, it may take quite a while to get cheap.
Cell phones, for example, are widely used in developing nations. Tech in general has been the best at reducing costs over time compared to things like food and energy which haven't really fallen in price.
