Everything has a place.. We use simulations when they make sense, for all other things we use practical application. I use simulation software primarily for designing my camshafts and engine combinations.

The ability to put a cylinder head on a flow bench, gather port flow data, then throw a camshaft in the profiler and gather those numbers, then throw all of that into the matching engine simulation software and start building a new combination without having to assemble it is a great thing. That said, there are few times that things in the real world go the same when building that magical combination, and of course the second generation of it is always better than the first.
