What has changed since 1983?

This was my first "IDE" in the late 1990's - Turbo Pascal 7 - code was not case-sensitive and Object Orientated programming was just sticking its head out, those who were lucky enough had dial-up internet and computers were still getting faster and faster every year almost doubling in processing power every year. IDEs that could autocomplete your code as you type were clunky and slow, online tutorials were scarce (if you had internet access) and developers were seen as geeks / nerds ... at least that was my experience.

What has changed since then?
