I would argue that software is NOT very different. In fact, it's still exactly the same, just wrapped in new words.

The entire web is still client/server. Web apps? Client / server. Databases? Client / server. Just because more apps now insist on having a server to store data instead of making use of the microcomputer that they're running on doesn't change the fact that the last 25 years has been a reinvention of the same concepts again and again.

And even when "Rich Internet Applications" was the craze of the 90s, that was still just client/server, the concept that 70s mainframes had been coping with - they were servers and served clients.

Sure, there are loads more programming languages now instead of the choice of C and C++ (and maybe Delphi?) for Windows in the 1990s but underneath it is still doing the same. Apart from now we have intermediate virtual machines and CLRs to intercede, perhaps unnecessarily?
