I had read all of my own published in 1970 books, so I dived into the garage to delve into the overflow bookcases and came up with one of Jack’s books, an SF book – Tower of Glass by Robert Silverberg, it was published in the US in 1970. It’s a good long while since I read any science fiction.

Simeon Krug is fabulously wealthy. He has created a community of androids, three different grades, Alphas, Betas and Gammas, they are made in vats starting with a sort of chemical soup and then they are given a training to learn how to become almost human, to understand their needs, the Alphas being the closest to being human. They look similar to humans, apart from their skin being red. The androids exist to do the dirty work and make life easier for humans.

Simeon Krug, their creator has moved on to a new project and he has become obsessed, he has designed a massive tower of glass and he hopes that as it reaches far into space he’ll be able to communicate with other galaxies, one in particular which is sending signals which can’t be deciphered.   .

Unknown to Krug the androids have set up chapels where they can worship Krug their creator, but he does know about the AEP which is a political group founded by disgruntled androids who are determined to gain equal rights with the humans. They want it to be made illegal for them to be sold and for anyone harming them to be held responsible legally.

So there are parallels with slavery, and social inequalities, but also the dangers of creating what could be superior beings which could take over society if they felt that way inclined.

Fifty-four years ago Robert Silverberg was imagining an AI takeover, except nowadays no androids are required, just computers.

This was a surprisingly good read, although I don’t really know why I was surprised as Silverberg was one of the best SF authors of his time. I have read a few of his previous books, but decades ago.
