Sun believes that the future of software development is the Internet, and Java and Solaris are the backbone of the Internet, so you should be using Sun's technology. I don't know for sure where he got his statistics. I was polite enough not to mention this in the discussion. He did also talk about XML and the SOAP initiative. Software development is an art.
Different developers have talents in different areas.
The most important thing about your future as a software developer is enjoying what you do, and loving what you do if possible. If you don't love developing software, you won't spend enough time keeping up with the technological changes. As far as Borland specifically is concerned, we have always embraced open standards. We specialize in making the hard things easy. Claudio and I summed it up by saying that you can rely on Borland tools to support the important technology you will need in the future, and help you enjoy developing software for it.
