This film is great because it not only illustrates the wonderful abilities of early computers but also emphasizes the humans who build them. Something I don’t see as a focal point nowadays
I seem to recall software having credits in the eighties and nineties
This having stopped is partly a side-effect of the “eternal beta” state of software.
“Thomas Knoll” is forever imprinted in my memory.
In part because programs back then were written by one or at most a handful of people that could be easily credited in the "About" box or equivalent. If you wanted a list of the authors of say Microsoft Excel or Adobe Illustrator today, the issue is that literally thousands of programmers contributed to them.
