The problem with this argument is that LISP was popular when there was no need to build extremely complex systems with a programming language. So you could build simple data processing apps with LISP, but nowadays writing a program is not just about algorithms but in fact mostly about utilizing APIs provided by device and service vendors. When you build an iPhone app with Objective-C, you use the [object] [message] paradigm but it's still complex, and it's not because of the message passing paradigm itself, but because of the complex Cocoa APIs it needs to use.
