 Actually, I think the use of disassemblers et al has fallen away.
Modern processors have so many peephole optimizations and out-of-order
execution streams that converting an executable back to assembly source is
almost meaningless -- and getting back to a high-level language is near
impossible. One would have to be an expert at the assembly for a processor
to have any chance of understanding the result.
