You don't want your website to be the same. First it needs to be created using the latest technologies. No problem there. It needs to work on the latest platforms, touch pads or whatever, again not a problem. Ok so what is the problem? It's what is just over the horizon, what is coming next. Can your website adapt, adopt the newest technology or are you going to be looking at starting again when a new something comes along you need to work with?
The websites we build take into consideration these unknowns. It won't be locked into one technology or another, it can adapt to whatever comes along.
