Neil Armstrong died on August 25, 2012. He was the first man to walk on the moon. (Since they always say this I wonder if Women walked on the moon earlier.) Ray Bradbury died on June 5, 2012, though on this (and perhaps other) blogs with was overshadowed by death of Mihai Patrascu on the same day.
When man landed on the moon I thought that this would be a common thing- that we'd goto the moon about once a year. In the end only 12 people walked on the moon and we stopped going in 1972. See here for details.
Why didn't we go more often? Maybe there wasn't much to see- you see one moonrock you've seen them all. Are unmanned flights much better in terms of science-for-the-money? I suspect yes. Also, one reason America put men on the moon was to beat the Russians to it. Once we already did that, the point was made, so no reason to go again.
If we went now it would cost much less. So perhaps we should have waited for the technology to catch up and go later for much cheaper. That's not quite right- one reason we have some of the technology is that we went then. But in some areas- computers in particular- certainly we would have still made progress without going to the moon. On the other hand going to the moon when we did was quite inspiring to some people. (Are you one of those people?)
Ray Bradbury's classic Farenheit 451 was about censorship- the government had firemen who burned books. Books made of paper. I suspect that within 10 years e-books will be the standard (some exceptions- Art books, maybe some Math books). Will that make censorship easier or harder? The Arab Spring was caused partially because the government could not control social media. However, in China the government is pretty good at blocking access to the Web. But still, some gets through. So to rephrase the question- does current technology make censorship easier or harder? I don't have an answer to this question- but I invite your intelligent commentary.
Ray Bradbury himself has said that the book was also about people choosing a shallow culture (e.g., TV over books). Modern technology has been a mixed bag for this. Some TV shows will one day (or even now) be seen as classics (e.g., The Simpsons) while others are of course going to be seen as vapid, shallow, and not worth much (e.g., Madmen).
