The Lego approach has been the holy grail of software development at least back into the 80's with OOP. Yet it still requires programmers who know about data structures, algorithms, etc. to write software. Even if they're just cobbling together libraries, there is still a lot of additional functionality required--not just 'glue' code.
All we have now are improvements in efficiency (great, mind you), with operational improvements like IaaS and development improvements with the great OSS that we have now. It will require a sea change in the field of comp sci. to achieve Lego-like orders of magnitude improvements.
