Gary Bernhardt argues that software history moves in reactions to earlier tools, and that new tools are not simply better in every way. He distinguishes capability (what a tool allows) from suitability (what it fits), and warns against repeating past mistaken reactions.

Veritasium's Derek Muller spends an hour in a silent, dark anechoic chamber at BYU to test the claim that 45 minutes is the most anyone can bear. He reports on his experience and other people's reactions.

Gameplay footage of the original 1986 Macintosh version of Dark Castle by Silicon Beach Software. The uploader argues the original is a great game that was tarnished by inferior ports.
