Much has been written about Gateway; I recommend Jo Walton’s reflections on Tor blog. What impresses me most is the complexity of the protagonist and his relationship with people and machines. Pohl was way ahead of his time in foreseeing the problematic effects of humans outsourcing themselves–and the services of fellow humans. Looking back on Gateway also reminds me of a time when, despite all our human problems, people still flung themselves out into space. What has become of that spirit today?
