These 100% AI generated posts about taste have to be some elaborate performance art piece, I genuinely do not understand how someone could think it a good idea "write" this.
In either case, taste being all that's left doesn't really help at all since whatever FAANG or top startups do is by definition good taste. Same for fashion, art and so on with the top being suitably defined. Slim fit was all the rage until all the uncool people got in and that's what ended the trend and not any friction or utility.
It's also just patently false. Taste is not all that is left. Are software engineers really so full of hubris that they thought coding is all that there is to making a product?
