It's a lot nicer than having the same logic in 2 languages and trying to keep them in sync – whether doing it by hand or with an LLM. One of the big rules is don't repeat yourself – much of the logic only needs to be written once (except UI)
Rust is uncompetitive for the use case of sharing logic between mobile apps. Kotlin has Swift interop and KMP is a mature tech by this point.

When Chrome 1.0 came out in 2008, it only ran on Windows, and it couldn't do basic things like print or export to PDF, didn't have any accessibility, didn't work in RTL languages, and didn't have any graphics acceleration, among other limitations. Don't get me wrong, it was a marvelous piece of engineering - but it was extremely incomplete. By the time it was what we think of as a modern, complete browser, they had m…
I agree with what you're saying that it's not exactly what we're seeing which makes it not as simple. However, I've seen this play out in many a big companies where there's a big mess going on. Answer is always similar pointing to -> "clearly it's not simple" and that's kind of the whole point. They made it not simple. 3k ENGINEERS, my sweet dude. THREE THOUSAND. By any and all account that's half as much as current…

#863Numbers from GPT Astra - Shopify has 3000 engineers as of 2026 - Google Chrome when released in 2008 conservatively had ~ 60 engineers. - GTA 5 in its credits had 150 software engineers. Surprising even to me who has had many an experience of being in a bloated FAANG team, this 150 includes GTA Online! In a sane society, Shopify’s opinion on anything engineering related would be thrown into rubbish because they seem…
Re: Shopify is moving from React Native back to Swift and Kotlin
#864I agree w/ advising people to move off React Native, though I think the story that "LLM enabled an otherwise too-expensive migration to consider" is not correct. I say this because I was part of a migration from a mid-size React Native app to a Swift/Kotlin native app redo. I did the majority of the technical work on it. The majority of the work occurred before January 2026 and without LLM code assistance, though lat…
I thought I read somewhere that this is what prompted the move. I don't use RN, but apparently the new architecture isn't exactly a drop-in replacement.

I suspect the vast majority of Shopify engineers never touch the core Shopify experience, but work on the long tail of invisible things that are nevertheless considered important. I'm talking along the lines of "direct integration with bank X for UPI in India to save 0.3% on payment costs in scenario Y."

Rubbish. Most of the stuff you’re listing is handled by OS and frameworks themselves, you don’t need hundreds of SE to handle RTL or a11y. I work in one of those companies, most people just regurgitate existing shit into another form of shit and collect salary (not complaining, as I’m one of them, but let’s be honest).

Recently listened is an automatic list like a log, not user curated. I would never expect to be able to delete things from that list.
I don't need an audit log for my audio. What I do need however is to remove something so it doesn't influence the algorithm. I may not remember every time I play music for a kid to turn on the right mode.

What are we talking about here - Spotify or Shopify ? If Shopify - and you are concerned about their engineering teams, please consider that Shopify's revenue grew from roughly $205 million in 2015 to $11.56 billion in 2025, reflecting an explosive compound annual growth rate (CAGR) of over 45% across the past decade. Market validates ! I have nothing to add about Spotify - I use it to listen to music and it works we…
Both. The post is about Shopify, but some of the comments expanded the conversation to include Spotify as well.
