I might argue that building a bridge is harder now taking the whole process into account (just the metallurgy is vastly more complex); but they don't fall down as often. Which they often did in early railroad days thanks to hidden cracks in the metal that were both frequent and undetectable back then. But ordering a bridge to be built might be easier, now.

Specifying routines completely disambiguously will always be hard, but I do think techniques will come along to provide the equivalent of railings and safety nets while you do this; such as AI to query you about what you really want to happen, and to draw your attention to edge cases and unusual combinations of circumstances that you need to make a clear decision about.
