Getting laid off sucks, but this comment isn't about that. What I noticed when I read the post is that the website isn't very good. It's laggy, as in slow to load, scroll, and for the mouse-hover stuff to respond, and this is on a fancy modern macbook. It seems to focus on pretty modern web aesthetic over presenting content. This is exactly the kind of website that makes me bemoan the tendency to prioritize looking better than a simple website when comparing 2 static images, and not prioritizing the experience of actually using the website.
I find these things have a real "well it works on my machine" about them. Whereas sites that stick to simple tech (ex. HN) are far more likely to work well on all machines.
The website works smoothly on my Pixel 6A. Not sure if it's JavaScript or some other software issues taking up your Mac's hardware resources.
Scroll perf on that site is terrible in Chrome on my S23 Ultra. It's much smoother (but still kinda laggy) in Firefox. Weird.
Browses very smoothly on my iPhone and it looks great.
