Full disclosure: I posted this on the YouTube comments as well but am curious as to y'all's opinions.
This is the first time I've left a comment on one of your videos due to an unhappy emotion but felt a need to write my thoughts somewhere they could, ostensibly, be seen. While a shift from X86 is indeed inevitable I disagree with the notion proposed by the choice to compare an M1 Mac to a Custom PC, being that all computers will over time tend towards less serviceable, less upgrade-able, and nearly in-customizable due to the power consumption and efficiency differential between the two. For evidence, I present the audiophile and keyboard markets. While they have both been generally standardized they have actually become more customizable as a result of the extremely dedicated hobbyists who are willing to pay more for less efficient and yet more effective products. I foresee a similar future for the computer market; the HPs and Dells of the world will begin delivering more M1 Mac-like systems as their users expect and require a high amount of energy and space efficiency; the more enthusiast focused brands will likely transition to a model of less more gainful sales instead of the current more less gainful sales and still provide systems that allow their users high customization and higher energy bills.
As an aside, I foresee the efficiency of materials as being of greater import than that of energy as the amount of useful energy in our reach dwarfs the amount of matter, especially that of any specific element, in our reach. I would also argue that over time the ability to swap out broken or outdated components is considerably more silicon efficient than the smaller system that will be ready for the trash chute as soon as any part breaks or becomes outdated.
