Rick Hartley's content is fantastic, but I think it caused collateral damage by making hobbyists who work with 8-bit microcontrollers and I2C believe they need to follow the same rules that must be followed for GPUs and PC motherboards. It's not Rick's fault, but it's a matter of the cult-like following he's developed among some hobbyists. Old-timers on PCB design forums try to impress and intimidate novices by citing his advice without really understanding if it's relevant. And most of the time, it isn't.

A lot of his videos should be prefaced by "it's interesting, but you don't need to worry about it unless you're working on the types of projects I'm paid to work on." Without this disclaimer, PCB design becomes less accessible. It's akin to teaching basic chemistry by starting with quantum foundations and insisting that everything must be derived from that.
