Yeah, by 1995, Visual Basic / C++, Delphi / Borland C++, and Symantec C++ were all-conquering.

A few years before, it was very different - VisualAge and Rational Application Developer were the big names in the early 90s in "professional" IDEs. Interface Builder for university spin-outs or funky startups (and SunWorks / Forte Studio for the less-funky ones). CodeWarrior on the Mac (perhaps with THINK! hanging on too). I think Softbench was popular for scientific software, but I never actually saw it myself.

And then just a few years later, the rise of Java turned things upside down again and we got Jbuilder, Visual Cafe, & NetBeans as the beginning of yet another new wave. The Visual Studio suite really began to take off around then, too.

In short, the 90s were a time of huge change and the author seems to have missed most of it!

An all-in-one like Rational Rose may be making a comeback in terms of these agentic AI projects, because now you actually can turn a spec into code without layers of tagging and UML.
