I've built several production quality, mid-sized apps in Phoenix/Elixir over the last year using Claude Code (CC).
In my experience, it's great, I had better results with this stack than I had with Django when using purely CC.
It's token efficient (because of code generator), has great static analysis, and terse (because functional). Phoenix even generates an Agents.md
The apps themselves are highly scalable and look great.
We got pretty far without a single hallucinated citation (because they simply didn't exist). It's really simple: check your references, or don't bother of publishing. It's not a high hurdle.
I get this all the time with Brave, and especially in Private Windows. It's the number one reason I don't use Google Search anymore. I've used Brave search for a while, what do you use? Do you have a way to prevent the captchas?
This is a strong disagree from me. What this is implying is that the customer now has to buy into two ecosystems: the expensive, Dodgers, tickets, and stadium world; and the far more perilous, casino in your pocket, attention sucking, hell, that's smartphones. Countless articles are being written on the effect of smartphones on the elderly (and teens). But you know what? Fuck'em. Because progress.
Another comment suggested grandfathering in customers like this. Sure, that's one idea. But generally, don't punish the masses because of the crimes of the few.
I'm certain VIPs don't scan their phones when they come to the game. This man is nothing short of a VIP.
I've built with GSD, and experimented with rolling my own. I think GSD is good if you don't know exactly what you want to build, but you only have a vague idea. However, if the opposite is true (and I believe it should be), then GSD has a lot of overhead, and costs a lot of tokens.
Subjectively, my GSD apps looked very much like AI slop (the app itself, not the code), and felt soulless.
Others have echoed the same, but I also switched from VSCode to Zed, but then put in the effort to learn Neovim (Lazyvim) properly, and I haven't looked back. Writing code feels exciting again.
I recommend something like https://github.com/adomokos/Vim-Katas to accelerate muscle memory.
And also Vimium in the browser is great.
