The lack of focus I feel like comes from the fact that his audience is an amalgamation of multiple groups, much of which is the "tech is over, it's all grifters now" cadre, so a lot of this isn't really meant to be a persuasive argument of anything but rather just a dumping ground of grievances.
I alluded to finding him an unreliable narrator of this topic, and this is why. So much of this audience is so fully committed to "this is spicy autocomplete, a totally non-functional grift on par with NFTs" as a position that it compromises any of the other points he's trying to make.
FWIW I do find some things of his sympathetic - particularly around how much structural risk we're taking on every time the VCs decide to line up the hype cannon behind something. That said, I think it's also fair to say that this is my projection of his argument, because his actual arguments are often too muddied to even draw that level of specificity.
[edit] I continue to follow Ed's writing because a) I think there are glimmers or something in there and b) I treat it as a temperature read of a substantial minority of public opinion. The level of disillusionment and rising anger against our industry is concerning.
