The rougher The Metamorphosis of Prime Intellect by Roger Williams is also worth trying:

Also A Fire Upon the Deep by Vernor Vinge, and Ken MacLeod's Fall Revolution series. The latter can be read out of order; I read The Cassini Division before any of the others. Excession by Iain M. Banks is also one of my favorites, though it has a significant learning curve if you haven't read any of his Culture books before. All of these have things to say about runaway technological change and superintelligence. They all have a high "sensawunda" index, for those who recognize this old SF fan term.
[1] I have read and enjoyed most of Stross's output, but it has a lot of thematic variations and someone who loved Accelerando may not care for e.g. Rule 34.
