Here’s another science-fiction tetralogy for you to read that is both entertaining and thought-provoking. The four books in Rudy Rucker’s “Ware” Tetralogy are:
- Software
- Wetware
- Freeware
- Realware
From Wikipedia:
The closest to the cyberpunk genre of all his works, the tetralogy explores themes such as rapid technological change, generational differences, consciousness, mortality and recreational drug use.
Pretty wild stuff!

Following the mortality link brought me to a page on Death. The page on Death had a link to an intriguing statue of a shrouded skeleton in Trier Cathedral – the oldest one in Germany. Brother Lew’s wife’s family tree (maiden name is Trier) traces back to that place – very interesting! You never know what a blog post will reveal.
