What a ridiculous comment. You and your videos are a delight, and if that person doesn't vibe with your video style or personality, that's on them. Glad you aren't taking that comment to heart.

Thinking about the logistics of creating a seamless loop that's long enough to not be obviously a loop, paired with all the other elements of convincingly "faking it," and how it's way more effort than riding a horse across the nether roof for four days.
Sorry you both had to deal with that person.

It blows my mind that someone would think that. Like, not only is it harmful to put the blame on accessibility features for misuse by pro-genAI folks, but the alt attribute for images has been around since the 1990s, so it's also just wildly inaccurate.
