I have no idea, I hope people like Trent Reznor and Tina Fey are. Bukowski (rip) should be and most likely will still be read then. Neil degrasse Tyson, David Attenborough are likely candidates too. I hope people get to experience those voices... Hawking definitely. I think with people being more active online and leaving more traces behind will make it a lot easier for those in the future to find what entertained us in the past.
