Ajit Jaokar quotes from a Tim Berners Lee keynote at 3GSM:
Web 2.0 community Web sites, eBay, and Flickr are possible because the Web standards, in turn, were widely implemented in an interoperable way, before those innovations. The same for the wikis, like Wikipedia, and blogs, and so on. The Web is a huge platform for innovation because of those standards. Any new genre of communication, any new social networking idea, immediately can gain the value of unexpected re-use by people across the world.
There is a very important difference in attitude between a foundation technology and well let’s call it a ceiling technology. A foundation technology is designed to enable innovation, to be the base which will support other even more powerful things to come. A ceiling technology is not. It is designed to provide a value, and for its provider to cash in and cash out. Proprietary music download systems are ceiling technologies to the extent that the technologists design to be also being the only store in town, rather than creating an open market. Though putting a lid on further innovation, they are still providing a service, and making sure they profit from it.
Ceiling technologies are the end of the road for innovation.
When you want to make a foundation technology, you need to look ahead. You need to put aside the short term return on investment questions and look at the long term.
