<p>I recently saw a blog post [1] about a famous Haskel shop moving away from Haskell to Python because the iteration speed with LLMs was just that much better. There is so much React in training data, TS compile times are minimal compared to Rust and similar.<p>I suspect user facing/fast moving code (UX layer) will move to dynamic systems with fast iteration times. Infra layer will move towards safe systems level environments like Rust. I'm not sure where Java/C# lands in all of this - it's kind of the middle ground between these two worlds but the tradeoffs change drastically with LLMs - my gut feeling says that TS/Python is good enough for UX work and Rust is better for systems work so it gets less popular going forward.<p>[1] <a href="https://avi.press/posts/2026-07-10-after-7-years-in-production-scarf-has-reluctantly-moved-away-from-haskell.html" rel="nofollow">https://avi.press/posts/2026-07-10-after-7-years-in-producti...</a></p>

<p>Same here - it's probably that OpenAI needs to buy goodwill with developers to infiltrate corps and Anthropic is trying to squeeze the lead into revenue. The only question is - how much longer can OpenAI burn money before it needs to start showing signs of profitability</p>

<p>> Some of the issues mentioned above like dead code removal, code duplication, unreachable code are already solved using deterministic linters for quite a while now for most language ecosystems.<p>I have legacy endpoints that are no longer used in practice, there for historical reasons, intertwined with existing code etc. They might be marked obsolete, services implementing it are not - agent greps those, builds off of them - produces half legacy garbage.<p>Linters only handle trivial cases most of us already solved.</p>

<p>>You can build application outside of container, but run it in container. I think that it is simpler workflow, than everything in container (when you actually need to develop it with IDE).<p>At this point I will not do any dev outside of a container - so many things can be supply chained in the OSS dev stack it's just not worth it, and once you get used to developing in containers it's actually a lot cleaner to move between hosts - you're essentially treating your client as a remote terminal.<p>If you're doing web dev work in this day an age SSH with tmux or some editor with SSH server support should be your dev setup.</p>

<p>It's not about time efficiency more about convince. It sounds trivial but sometimes it's really useful to be able to do things hands free/without having to move - worth spending the time to install/setup all of this once.<p>I'm in the middle of remodeling a new apartment and all my switches are smart. I won't even have physical switches for some fixtures like window rollers.</p>

<p>I have dimmable lights I need the main light at 20% to read a book and it's useful to whisper to my assistant instead of walking across the room. I really don't get the comment - just because you can't envision a usecase doesn't mean it's not useful to me. Wife was a total skeptic about smart home stuff but having alexa control the bedroom lights while changing diapers or preparing bottles at night for her to switch to using it constantly.<p>I would have preferred Siri because one less provider but it's just unbelievably bad for this day and age.</p>

<p>This is all assuming tests measured anything valuable in the first place. In my experience standardized tests were always flawed and most of my peers knew shit about the subjects they passed in top % a year after. If AI breaks the current education system that's a win in my book.</p>

<p>Why ? If it's shared reads and scoped writes (read-only look up, output to a thread owned buffer span) concurrency seems pretty straightforward.<p>Rust can only prove a limited subset of correct programs to be safe, when you're doing bare metal stuff you've often not in that subsystem and drop down to unsafe. I'm guessing there's always stuff that's not perf critical and can live in Rust sandbox - so not saying no wins - but it doesn't sound like Rust is a no-brainer.</p>

<p>Usually I describe the problem, explore a bit with LLM iteratively. Then I switch to creating a plan when I have enough insight (and the LLM has it in context/same session as exploration), specifying all the things I'm trying to accomplish.<p>Then I just iterate with LLM - I let it start writing stuff in YOLO mode and check on what it's doing in the code steering it in the direction I want.<p>Usually the code LLM generates will work but is kind of garbage - but I can easily steer it towards better implementations.<p>Sometimes using an LLM is theoretically slower than hand-rolling - if I just sat down and focused I could outperform the iteration and the waiting, especially considering how stupid agents are at running expensive builds/test suites (with a bunch of explicit instructions in skills/claude/agents.md). But the practical improvement of going with LLM is that you have a bunch of thinking traces saved as a part of your iteration proces - it's really easy to get back into flow. This is a huge productivity win for me given how many interruptions I have in my work day. Like so many people like to point out - writing code ends up being less and less of your time as you level up in your career.</p>
