Unfair to cite the 1950s and the _very_ first computer languages, we just didn't have enough experience in this whole thing. See the British guy who walking away from his (very rare I think) computer came to the sudden realization he would be spending a great deal of the rest of his life fixing code bugs, including his own.
More fruitful would be for example the CASE era, per Wikipedia and my vague memory "CASE tools were at their peak in the early 1990s. According to the PC Magazine of January 1990, over 100 companies were offering nearly 200 different CASE tools." (The real action where I was in those days was with PCs that had become seriously capable with 386 and 486 CPUs and Windows 3.0 and beyond.)
