Ignores the totally exceptional nature of some of the US changes/instabilities of this administration. I say "not true" because that is my read of where things are going, regardless of preferences.
Not true. Some, like myself, love the idea of the shining city on the hill, although we often find the behavior of the actual city less than shining.
I would like for the US to continue being a beacon of freedom where people can come and build great lives.
But that is not the direction we are going, and one might reasonably forecast that no country can maintain indefinite dominance. Paul Kennedy wrote "The Rise and Fall of the Great Powers" almost 40 years ago. Regression to the mean and all that, but also, great powers tend to overstep.
I'm gradually tuning out Hacker News, because it persistently tries to ignore the politics that are destroying the United States and freedom of enquiry.
There is a dead comment below that tries to raise an argument but was killed instead. This is no longer a place to go to discuss ideas.
I think you are criticizing an idea for not being a study. I think it's a reasonable and interesting idea, but at most it is something to consider, not some infallible axiom. More akin to "the Peter Principle" than a theorem.
Point 2 is... neither important nor really germane. (I don't care what engineers say, and Musk isn't an engineer anyway.) The point is that people understand their customer bases, and sell to them, and then imagine that means they understand how to succeed in the business their customers are in, and... not so.
It's basically a reminder that understanding the customer is everything. No matter how good the tech is, if you don't solve the customer's problem... they aren't buying.
Sure, in all cases, acquiring knowledge of what the (potential) customers want is difficult. The point of the article is that vendors of layer N tend to think they know what it takes to succeed at layer N+1, but they don't, because that customer base (N+2) is different.
The other (more important, maybe) thing the article points out is that building layer N-1 turns out to be easier, because layer N is the customer and understands those needs already.
This. Actually, I would buy a cheap guitar (but not from Amazon), say $400-500, for a purpose like having one to place when visiting relatives at Christmas. But I wouldn't buy a nice guitar without inspecting and playing it.
I would think the sensitivity to this would depend a lot on family size. Shopping for just myself... it doesn't matter much. Shopping for a family of 4 would be very different.
1) When I really need it within a couple of days and can't quickly find it locally
2) When it isn't carried locally (the local retail stock is a lot thinner than 20 years ago)
3) If there is a BIG price difference -- used to be common but now much rarer. As you say, Amazon's prices are often worse than buying locally.
4) When I need it shipped somewhere else. I usually spend Christmas, for example in another city, and it is impractical to bring a bunch of presents. Amazon is good for situations like that.
I dislike Amazon, but they are now so dominant it is hard to avoid them.
I dislike Home Depot's politics so much that I make a point of never going there.
In general, I prefer buying local, because it makes my community healthier -- more jobs, directly and indirectly, more options to buy something this afternoon if I really need it. But the reality is that many items are already very difficult to buy. Some of that was true 20 years ago, but it's gotten much worse.
I don't think that works either. I'm not a meal planner, but I will usually just make do with food I've already bought. Nothing appeals? I might eat cheese toast or yogurt.
Not a European, but this rings true for me in the US. I'll go out and get something, in part, because it is less lonely and feels more attached to life, to the world. Endless deliveries actually make that worse. I started buying more things locally in part because of that.
It's also one of the reasons I don't really like working from home.
