This may not mean a lot to non-sci-fi fans, or even non-UK sci-fi fans.
Aldiss was a bit of a doyen in the sc-fi genre, one of the thoughtful authors, and had one short story turned into a very good film by Kubric/Spielberg - AI.
His "Helliconia" trilogy was complex and inventive - and something I should read again.
It seems he was of the opinion that sci-fi does not really predict the future but was another view on the condition of mankind. (Womankind might differ!)
Helliconia is one of my favourite triologies. I also loved Aldiss' short stories and his novel "Hothouse".
A name from my younger years. Farewell, Mr. Aldiss.
