So, the author here is arguing that between ready reference/help on the web and TDD, that programmers today can be _100x_ more productive than they were in the 80s? Add a dash of strongly-typed functional programming and we can be 1000x more productive?
I agree that these tools can be productivity enhancers, but if that factor is even 10x that would a huge claim, much less 1000x.
Especially if we break this down to working days. There are just about 200-250 per year. Could you really build a software that used to take 4 years to develop in a single day now? Even 100x would mean a years work in three days.
