I'm hoping they stick with the book's 'cassette futurism.' Remember that at one point they are selling pocket-sized VCRs at one of the markets, and the space ship pilot is afraid of a 'virus.'
When the book first came out there was nothing like it. Today, the book's ideas have been recycled dozens of times.
There's a great movie "Predestination." It's based on a book written in the 1950's and it uses a future that looks like something people in the 1950s would have imagined 1975 would look like.
