Not really. Most pyramids are throwaway. The web is 99% throwaway code. Businesses themselves are throwaway too, so a lot of software made by them and for them goes to bin after few years.

What remains? Projects that are so useful that dominate their niche. Windows, Linux. Office. Photoshop. CAD tools. I suspect VLC will remain, 7zip may too. Some of those tools are pyramids, some others aggregation of small artpieces. I don't think survival depends on whether or not the software is a pyramid or a thatch hut.
