One of the greatest sources of those Lem's "predictions" is his Summa Technologiae, which was recently translated into English - https://www.amazon.com/s?search-alias=stripbooks&field-isbn=...

It's from the 60s and contains strikingly good predictions on AI, SETI, Virtual Realities, nanotechnology, multiple universes, the future of our civilization etc.etc.

Also, if you're a fan of R.Kurzweil and others predicting the technological singularity - reading Golem XIV (from 80s.) - https://en.wikipedia.org/wiki/Golem_XIV - is a must.
