Jim's Reviews > The Door Into Summer

Another old favorite picked up as a downloadable audio book from the library. It was quite enjoyable in this medium & the reader was very good. Originally published in 1957, it is set in 'the future' years 1970 & 2000. The idea of traveling into the future via 'cold sleep' was a pretty popular until sometime in the 70's, but cutting edge at this time, I think. Haven't heard about it in humans for years.

The hero, Dan, is an engineer & inventor. His genius isn't in break through technology, but in putting together mostly off-the-shelf parts to create really useful laborsaving devices. Steve Jobs type genius, timing, & design. Heinlein's discussion of this tech timing over the course of the book is very practical & interesting. It's amazing how much supporting technology there has to be for every major breakthrough.

Engineering is the art of the practical and depends more on the total state of the art than it does on the individual engineer. When railroading time comes you can railroad-but not before. Look at poor Professor Langley, breaking his heart on a flying machine that should have flown-he had put the necessary genius in it-but he was just a few years too early to enjoy the benefit of collateral art he needed and did not have. Or take the great Leonardo daVinci, so far out of his time that his most brilliant concepts were utterly unbuildable.

It was Heinlein's genius to take this a step further into the prosaic & make it sound so easy & obvious.

Amazingly little real thought had been given to housework, even though it is at least 50 per cent of all work in the world. The women's magazines talked about "labor saving in the home" and "functional kitchens," but it was just prattle; their pretty pictures showed living-working arrangements essentially no better than those in Shakespeare's day; the horse-to-jet-plane revolution had not reached the home.

Of course, Heinlein got a lot wrong about the future, but that wasn't too bad. Most obviously, we still don't have most of the devices that he describes. I loved his idea of Thorsen Memory tubes & macro programming, even though both are silly & simplistic. He had helicopter buses & completely missed the idea of the Internet - overall communications or electronic databases - yet he had transmutation of elements. Not a bad reason, if incorrect, for getting off the gold standard & he had the timing pretty close.

The overall story was a pretty good one of love & betrayal. With the time travel tossed in, it got quite twisty - although I was a little disappointed the he seemed to try to obscure it a bit too much especially in the last conversation. That was too much as the character is supposed to be fairly intelligent.

And that brings me to the creep factor that really brings the book down for me - Dan's relationship with Ricky. (view spoiler)[ What do you call a guy who promises to marry a 10 year old when she grows up & then does it without even knowing her as an adult? Seriously, he did & the scene was so poorly done, too. Ricky talks like the little girl she is yet Dan treats her like the full grown woman she will be. It was seriously icky. (hide spoiler)]

So it was a 4 star story with 1 star removed due to this one creepy factor. It's well worth reading or listening too, though. Glad I did again after all these years.
