Briefly surveys various proposed main bottlenecks for an intelligence explosion, and argues that none of them is going to be a major one:
Economic growth rate
Investment availability
Gathering of empirical information (experimentation, interacting with an environment)
Software complexity
Hardware demands vs. available hardware
Bandwidth
Lightspeed lags
