I noticed that there's a developing trend of "who manages to use the most CSS filters" among web developers, and it was there even before LLMs. Now that most of the web is slop in one form or another, and LLMs seem to have been trained on the worst of the worst, every other website uses an obscene amount of CSS backdrop-filter blur, which slows down software renderers and systems with older GPUs to a crawl.

When it comes to DeepL specifically, I once opened their main page and left my laptop for an hour, only to come back to it being steaming hot. Turns out there's a video around the bottom of the page (the "DeepL AI Labs" section) that got stuck in a SEEKING state, repeatedly triggering a pile of NextJS/React crap which would seek the video back, causing the SEEKING event and thus itself to be triggered again.

I wish Google would add client-side resource use to Web Vitals and start demoting poorly performing pages. I'm afraid this isn't going to change otherwise; with first complaints dating back to mid-2010s, browsers and Electron apps hogging RAM are far from new and yet web developers have only been getting increasingly disconnected from reality.
