Scince fiction writer and visionary Arthur C Clarke turned 90 on Sunday.
Best known for his blockbuster "2001: A Space Odyssey", he also wrote numerous other books and short stories.
I've devoured most of his works since I was 11 years old, amd marvelled at Clarke's optimistic vision of the future, and what we could achieve as a species. He made the future exciting. I couldn't wait for it to happen, and still can't :)
I hope you stay around till you're at least 100, Sir Arthur. We need more optimistic vision like yours.
