I wonder if it's counterproductive to tell every programmer they should know an entire book about SSDs (or DRAM, cf. Drepper), especially when the later chapters tell you that you have no control over the stuff you learned in the earlier chapters due to the FTL and filesystem.
If we had always said "why should a programmer read about X" we'd still be stuck with text based OSes. A lot of the innovations PARC came up with (GUI etc) came from bringing in anthropologists and psychologists. Stepping outside your comfort zone is how cool things happen.
