If you have to ask why TeX is still used as a tool, then you don't understand what TeX is. You should not view it as a program or a fad that gets outdated when the latest version of BozOS Release 9 comes out. TeX is a theoretical solution to the problem of computer typesetting. As an article ages but still remains a reference until the science has advanced, TeX stays the same until somebody discovers something that makes it a footnote in history.
The fact that you can install a program called TeX on your computer is marginally irrelevant.
The question you want to ask is: after Knuth has solved to the best of his ability the general problem of computer typesetting, why hasn't anyone bridged his theory with the front-ends that everyone uses? My take is: the shiny tools that exist were good enough for most people to toy with.
