Too much sci fi. All i wanted was a Ready Player Two, maybe thats the reason for this negative impact. Though there were a lode of relatable Video games and pop culture references, book lost me with the Far side of the moon or maybe the hidden history plot. Ending added to the woe. But it was as an easy fun read and i had it covered in two days. 
 Nevertheless I am getting Lightman playlist compiled along with a Cosmos rewatch. 
 And a later me found out where he picked some concept from - The Sentinel, Arthur C Clarke :)
