Extremely annoying to view. Please show the entire slides at once, or at least have an option for this. If it is important to show them one part at a time, please indicate how many steps there are on this slide, so that I can press next quickly to skip the "animation" without risking skipping to the next slide. Can't comment on the content as I was too annoyed with the UX to read past a few slides.
Then just don't comment at all.
Someone generously put a slide deck of their talk online. A deck that was actually designed to be delivered by the author, probably while standing next to them, at an event. Obviously, it's going to be slightly out of context for people who come across it on the internet (esp with no video/audio to accompany it).
If people wrote their slides for the internet first, imagine how boring all the conference talks would be.
