I also winced at "impossibly fast" and realize that it must refer to some technical perspective that is lost on most users. I'm not a front end dev, I use linear, I'd say I didn't notice speed, it seems to work about the same as any other web app. I don't doubt it's got cool optimizations, but I think they're lost on most people that use it. (I don't mean to say optimization isn't cool)

We almost forgot that's the point. Speed is good design, the absence of something being in the way. You notice a janky cross platform app, bad electron implementation, or SharePoint, because of how much speed has been taken away instead of how much has been preserved.

It's not the whole of good design though, just a pretty fundamental part.

Sports cars can go fast even though they totally don't need to, their owners aren't necessarily taking them to the track, but if they step on it, they go, it's power.

Second this. I use Linear as well and I didn't noticed anything close to "impossibly fast", it's faster than Jira for sure, but nothing spectacular.
