This is subtitled "A science fictional autobiography", and it is indeed about his career as an SF writer. I believe he published a separate, scientific, autobiography.
I'm very fond of SF author memoirs, and this is a good example of the genre. Clarke wasn't in the US, so he knew different people, and that makes it more interesting. Also, he was involved in quite a lot of space advocacy and science and engineering, and the mention that gets here is also fascinating.
