<p>Looks much better than when I last tried it! But I couldn't get it to work as well as Cursor for AI development, maybe I just need to get more used to it?<p>- I tried to use the Cursor Agent via ACP, it worked but it seemed markedly stupider than when I would use Cursor directly (saying that i18n strings were being used when they weren't, editing code differently than what I asked for, also when it is running terminal commands it seems to just say "Run Command: Terminal" and has no information on what's going on). Maybe I just need to not use Cursor Agent, but my company pays for it already so that's what I tried.<p>- Providing context is also cludgier - In cursor I often highlight specific chunks of code and add it to the AI context via Cmd+L, but I couldn't figure out any specific way of doing that with a keyboard in Zed besides clicking a tiny + button to add "Selection" to context, which got old fast.<p>- Maybe I just need to get used to it but reviewing code with the git integration is just hard for me to follow; one giant editor with every change in it is just harder for me to grok than showing each file one by one; so it was tiring to review the big changes produced by LLMs. Also, when you stage changes the file just stays where it is with a barely noticeable check in the checkbox in the sidebar - I prefer the behavior of Cursor where it actually moves the staged files to a separate section, but some kind of more obvious visual indication besides that perhaps would help. I did like the tree view, though!<p>- The tsgo and oxlint LSP servers kept crashing, which was frustrating. GraphQL LSP server also couldn't understand graphql.config.mjs, which is strange as that's supported out of box by graphql-config and works fine in Cursor/VSCode.<p>- I tried using a few of the different Edit Suggestion LLM options, but unfortunately Cursor is just way too good compared to any of them (slow, and just not very helpful in comparison).<p>- Just in general figuring out how to configure them is confusing, there's like 3-4 different places to configure agents and LLMs for different purposes, I found it very fragmented and confusing and the docs didn't make it particularly easy to set things up.<p>That all said, the performance was muuuuch better than Cursor. But the UX issues and general bugginess of ACP and these LSP plugins were impeding my workflow too much for me to tolerate it so back to Cursor for me. If anyone has tips on how I might make some of these better that would be cool, but if it's just inherent limitations then maybe I'll try again in 6 months or something.</p>

<p>Did you read what I said? The whole Japanese system is for profit and the one of the biggest reasons for Japan’s system being so pleasant is that it is done for commercial purposes.<p>If the incentives are right American companies can make good things, but usually they are not so because of poor policy.</p>

<p>Works in progress also had a great article recently (also discussed on hacker news) about how Japanese railways are private, profit earning real estate development corporations. [1]<p>Unfortunately, people from western countries have very negative views toward the privatization of mass transit despite the wild success that Japan has experienced. The model makes so much sense: if trains are just a way to get people to the real estate that you developed, then you’re going to make sure that the trains AND the destinations are really nice, which also turns out to be very lucrative  (at least in densely populated areas) as a cherry on top.<p>And even worse, like this commenter above alludes to, it is trendy in the West to believe that real estate developers are evil, and that corporations that make money are sucking the life out of society. This kind of degrowth populism pretty much guarantees that the successful Japanese model is out of reach for most countries, because it is exactly the pursuit of profit that makes Japan’s system so nice - not some edicts from a benevolent and extremely capable government.<p>[1] <a href="https://news.ycombinator.com/item?id=47762060">https://news.ycombinator.com/item?id=47762060</a></p>

<p>One example is that I have a fancy visualization in my app that is rendered in the server via RSC and just some interactive tidbits get sent to the client. If I packaged the whole visualization library it would have bloated my bundle size but instead I ship barely any JS and still get a nice interactive vector data viz experience. And the code just looks like normal react component nesting more or less.</p>

<p>China is giant and sprawling and they are able to do it.<p>That said this reply doesn’t actually address much of what the article talks about, most interestingly how rail companies are private and are also real estate developers. That thought process ought to make sense to Texans or something.</p>

<p>Hating Palantir without having any idea of what they are is the trendy thing to do. Their leaders are toxic which doesn’t help the case, but the core issue really is just that in this political climate, people all over the western world don’t trust their governments, and it’s also trendy to distrust anyone making money, as well as tech companies - especially those involved in data and AI related businesses - so the fact that Palantir makes these distrusted actors more competent while making money doing it, is seen as siding with the devil.<p>So it’s a trust problem, if the government were seen as effective and worthy then I want them to be effective, which includes using the data they collect effectively. In this climate trendy people would prefer that their corrupt government is also fully incompetent to limit the effect of the corruption.</p>

<p>I broadly agree with this, it really is all about trust. Just, as a company scales it’s hard to make sure that everybody in the team remains trustworthy – it isn’t just about personality and culture, it’s also about people actually having the skill, motivation, and track record of doing good work efficiently. Maybe AI‘s greatest value will be to allow teams to stay small, which reduces the difficulty of maintaining trust.</p>

<p>One time when I was living in Shanghai, I accidentally took the train to the wrong airport and had to take a cab to the other one. The cabbie was driving on the highway right at the speed limit, and I was worried I wouldn’t make my flight. I asked him if he could rush a bit, but he replied that he would not speed because 100% he would get a ticket.<p>It only doesn’t work if the system is half assed. But I agree that in low speed pedestrian areas, the built form is a better solution, but knowing you will get caught is also effective (if you accept the privacy tradeoffs).</p>
