Jun 01 @AdamRackis I am the employer. I got serious about simplifying things because I was sick of paying people like you ridiculous salaries to build incredibly basic software, and preserve the complexity that justifies their salaries. 3 0 0 0 229 .

Jun 01 @AdamRackis I’ve noticed a lot of your tweets try to make other people seem smaller so that you can feel bigger. “Most of us are busy doing *important* things” Also, you seem to be back pedaling? “Only works for splash pages”, “no it works for production”, “ok, but hAve yOu gOt a real Job?” 5 0 0 0 292 .
Jun 01 The level of arrogance and ignorance in these posts drives me crazy. It is 100% possible to build “software at scale” with simple solutions (including no build), *if* you put in the effort to figure it out. I’m confident in this take because I’ve spent a lot of time figuring those things out, all while being told by people like Adam that it’s not possible. I’m pretty sure “Works for splash pages” is meant to bait people like me for engagement. I wish it didn’t work, but it does. 14 1 6 4.5k 487 .
Jun 01 We started an experiment a year ago to build our React Native apps with a hybrid approach (stacked webviews that feel native), with some screens built in React Native where necessary. With the exception of chat UI - which is still hard to do with a webview because of keyboard UX - the screens we've built in html have been 1) Much easier to test (pull to refresh), 2) Much easier to implement simple state and navigation, 3) Much less prone to break, 4) Oddly more performant and less likely to drop frames - and we use Lottie to make things feel native. It's taken us a lot of iterations, but I genuinely think we've stumbled on something game changing with this approach - the big downside is the offline experience isn't great. But in almost every other area this approach wins. 3 0 1 368 785 .

May 31 Most companies don’t want you doing important things with their API and circumventing their UI, for various competitive reasons As agents become a thing, there will be more and more tension between these competing priorities, and my hunch is the consumer will probably lose. 3 0 0 223 276 .
May 31 He’s right. Remember the decades before typescript when there was nulls in products everywhere. Chaos! 0 0 0 206 102 .
May 31 We’ve done a lot more mobile dev in the last year and my biggest surprise has been that simply learning the core primitives doesn’t get you to “can build polished products out of the box” - I thought that’s what native dev had over the web, but it turns out it’s not true. 5 0 1 491 272 .

May 30 This is interesting. But if there's only marginal difference, shouldn't you do the one that builds the most goodwill and exposes most people to the product? 0 1 0 175 156 .
May 30 Using AI for non trivial long running work follows a similar graph to the Gartner hype cycle But you have to actually use it for hours a day, for a sustained period to internalise that. This might explain why CEOs of larger companies (including the AI cos themselves) are so hyperbolic - they’re not using it first hand for long enough to see it’s imperfections, and they’re drowning in the noise from all the people who are atop the peak of inflated expectations, and assuming they’re at the bottom of a hockey stick. 3 0 0 195 520 .

May 28 The key to building something *really* polished is the period after the "designs have been implemented" where the engineers, pms, designers do hundreds of use-tweak-test loops, see how it *feels*, and keep iterating til the end to end experience feels right. You can tell by using their products that Google just doesn't do this - it's ticket driven development - if it can't be described and added as a ticket, then it won't be done. 2 0 1 272 436 .
May 27 For a long time there haven’t been great examples to point to for “What are some html first apps that feel as polished/slick as Js SPAs” but Ronan’s stuff definitely hits that bar. So nice 2 0 1 306 188 .
May 27 If I were an investor looking to invest in one of AI coding tools (including Cursor, Windsurf, Devin etc), I would be putting my money on @codegen They are building really novel and valuable stuff, and unlike the others are actually under hyped right now 16 6 1 2.6k 256 .

May 26 When Devin came out I was like "Holy shit this might be it", but it's still not that much better than tools with no feedback loop. 0 0 0 296 130 .
May 26 The most pessimistic take on AI assisted software development is... There's a fundamental ceiling on how well apps can be built if there is no feedback loop (the coder can see and interact with the results of the code). A feedback loop requires reading and understanding the browser (and/or native apps). This presents 2 problems - The state of the art in browser interpretation even today, is still very low reliability. - Most apps have an obfuscation layer (react/next etc) between what's in the codebase and what the browser renders, making this harder. There is a real possibility that things improve, but don't reach to the point that even mid level developers can be removed. 0 0 0 672 687 .

May 21 Ok this is impressive from @cursor_ai using O3 Max. We've been building a hybrid boilerplate (similar to hotwire native) and doing some weird atypical stuff. Kept getting stuck on things that should be straightforward but weren't, and up to now Cursor was useless - none of the models seemed to *understand* what was happening. Just tried with O3 Max (thanks @Shpigford) and it got me a working solution in one pass. Not only that, it managed to build an understanding from the code that the previous models couldn't. 10 1 1 2k 522 .

May 21 I absolutely loathe bureaucracy and regulation, but I share the view that thinking that’s what’s behind the EU/US divide is incorrect. In the US, there is a pervasive desire for more-and-better, coupled with the absence of shame and cynicism (and then the obvious head start/rich-get-richer, network effects that compound that). It’s not the one-true-way - both have benefits and trade offs, and I like the European way. But you don’t get US level wealth by simply removing over regulation and keeping the culture the same. 4 0 0 427 525 .

May 19 In 2025, the top open source browser agent can still only reliably complete tasks 30% of the time. To replace real employees, this will need to get closer to 100%.
