Have you ever heard of the Kansas collaboration environment that the Self programming language used (it is the forerunner of all modern GUI-based collaboration systems, just as Smalltalk is the forerunner of all modern GUIs).

I'm using a 2018 Mac Mini with 16 GB of RAM and when I play games via steam, the temp seems to jump about 10-20 degrees.
