No, precisely the opposite should be said of engineers. Engineering is about reusing well-known techniques to achieve repeatable, predictable results whose timelines can be estimated. Engineering is not art. When civil engineers build new buildings or bridges (and I'm talking about your common building or bridge, not some iconic project), do they try to innovate and undertake to do things in some new-fangled way every time? No, because this would be extremely costly and dangerous and would render useless much of the past work that's been done testing materials and loads and so forth. When a method is known of constructing a bridge or an overpass that is both safe and economical, a good engineer should just keep doing that, with perhaps some adaption as appropriate on a case-by-case basis.

If software developers would stick with tried-and-true tools instead of inventing new frameworks to solve the same old problems and immediately obsoleting the "old" way of doing things each time, we'd have much less legacy code and likely would be much better at estimating software development tasks, and wouldn't have to solve the same problems over and over again.
