neehao··on Making Teenagers Read Newspapers. A Nationwide Experiment in French High Schools
fair. plausibly tested what's easy enough to do and still seems like a win. we need a separate treatment for increasing informativeness of news.

neehao··on Everything that's wrong with Google Search in one image
from a new customer perspective who just heard about midjourney, search may be a good spot to find alternate products. what google needs to know is if it is a navigational search and unless it keeps a long history, it may not know that. the simpler answer may be that companies who know you use a product like the one they make may just be willing to spend a bunch and google may be willing to add friction for the $.

neehao··on No clicks, no content: The unsustainable future of AI search
As Tyler Cowen says, solve for the equilibrium.

"Many widely used machine-learning models rely on copyrighted data. For instance, Google finds the most relevant web pages for a search term by relying on a machine learning model trained on copyrighted web data. But the use of copyrighted data by machine learning models that generate content (or give answers to search queries than link to sites with the answers) poses new (reasonable) questions about fair use. By not sharing the proceeds, such systems also kill the incentives to produce original content on which they rely. For instance, if we don’t incentivize content producers, e.g., people who respond to Stack Overflow questions, the ability of these models to answer questions in new areas is likely to be lower. The concern about fair use can be addressed by training on data from content producers who have opted to share their data. The second problem is more challenging. How do you build a system that shares proceeds with content producers?"

neehao··on Cognitive load is what matters
This article covers a lot of the points: https://www.gojiberries.io/building-together-separately-chal...

"A single page on Doordash can make upward of 1000 gRPC calls (see the interview). For many engineers, upward of a thousand network calls nicely illustrate the chaos and inefficiency unleashed by microservices. Engineers implicitly diff 1000+ gRPC calls with the orders of magnitude fewer calls made by a system designed by an architect looking at the problem afresh today. A 1000+ gRPC calls also seem like a perfect recipe for blowing up latency. There are more items in the debit column. Microservices can also increase the costs of monitoring, debugging, and deployment (and hence cause greater downtime and worse performance)."

neehao··on Perceived Breakfast Buffet Value Much Higher Than Cost
For the customer, breakfast can be expensive if they bought it from outside. I can imagine $50 for a filling breakfast for a family of 4. This is just good bundling.
neehao··on GPT-5
three points: 1. i have often wondered about whether rapid tech. progress makes underinvestment more likely.

2. ben evans frequently makes fun of the business value. pretty clear a lot of the models are commodotized.

3. strategically, the winners are platforms where the data are. if you have data in azure, that's where you will use your models. exclusive licensing could pull people to your cloud from on prem. so some gains may go to those companies ...
