many years ago when Hanami was just getting popular I remember doing benchmarks against Rails when it comes to SQL and was unpleasantly surprised when Rails' ActiveRecord ended up being much faster, despite "speed" being advertised as one of the advantages :-(
I found Ruby LLM to be surprisingly good - in terms of usability it's close to Vercel's AI framework.
It tries to strike a balance between working out of the box and being flexible... which has its challenges, still nice overall.
One big real-life pain I experienced is that caches don't always work, e.g. for xAI, since it only supports completions API and thought signatures are returned wrong.
Maybe my pockets are not deep enough, but I completely fail to understand the value proposition of iPad Air vs the regular iPad. If you want something powerful or big - go with Pro, if not - choose the "regular", much cheaper.
Another dimension to this is native vs 2nd language speakers.
For those of us who had to learn English, we put a lot of effort into grammar, while native speakers whip out half-baked sentences without a second thought.
