Lem is underappreciated. I've recently reread a book with his interviews Tako rzecze... Lem (in Russian, English version does not exist). This caused me to remember some of his works.

While he is a bit snobby and complaints too much, you can't deny he really envisioned huge amount of things to come. His imagination is next to none, and probably some things he described we will see only in the distant future, or maybe during the singularity, if it happens.
