Because to download and run it you need to have a laptop nearby to download and run it on, with the correct operating system and often additional dependencies too.
I do most of my research reading on my phone. I want to be able to understand things without breaking out a laptop.
There's a paper associated with it that you can read on your phone. And I don't think demo videos are really associated with "research". I agree they could've added both, but let's be honest here you'll have demo videos on this in the next 12 hours for sure.
That's a related complaint: everyone continues to insist on releasing papers as PDFs, ignoring the fact that those are still pretty nasty to read on a mobile device.
Sure, release a PDF (some people like those), but having an additional responsive web page version of a paper makes research much more readable to the majority of content consumption devices. It's 2023.
I'll generally use https://www.arxiv-vanity.com/ to generate those but that doesn't work with this specific paper since it's not hosted on arXiv.
fwiw, i know the topic of the thread has deviated, but i share the frustration about reading PDFs on my device. In my case, it's an accessibility issue - I can't see well, so zooming with reflow would make my life materially better since I'd be able to read research papers on my morning commute.
Sometimes users have needs that may seem superfluous and beg for a snarky reply, but there are often important reasons behind them, even though they may not be actionable.
I'd pay $x000 for an app that does some sort of intelligent pdf-to-epub conversion that doesn't require human-in-the-loop management/checking.
Why should we have any marketing materials, ever? Why do we show pictures of products? Sometimes people want to see the capabilities before they completely dive in and spend their time working on something.
