Disagree. I actually like the versatility of vocaloid, and similar programs. It has a different feel to it that I enjoy though there are some voicebanks who, when put in the right hands, can imitate human singers very well imo. SynthV vocals are an example of a really good program similar to vocaloid.

This somehow seems to be an unpopular opinion but I genuinely like Welegato from HnK and think they're an interesting character. I really also don't get why people keep calling them "dumb" when canonically they developed an interest in sciences and just happen to act all cute and peppy and dresses in skimpy outfits. Also I've seen some HnK fans refuse to call them Welegato because the don't like that name but it rubs me off the wrong way hearing that.
(this could have been longer but. I don't wanna ramble too long 💀)
Edit:// I think I was being too specific 💀
For a different unpopular opinion, I think mukbangs aren't that weird or bad (if you know who to watch). I sometimes like watching them while already eating. Y'know, as it was originally intended for.
