I dont really think so. I mean yea, too much money gets dumped into AI, but the dot com comparison doesn’t really work. The dot com bubble burst because investors realized that a ton of small companies(aunt-emmas-flowers.com or something), had no strategies and unsustainable business models. They were all massively overvalued. But Microsoft, Google, Tencent, Baidu are all large companies, they aren’t comparable and unlikely to suffer much if one of their investment fail. Additionally, AI is incredibly young and essentially still in beta, just because it works and can be used (and be profited from) doesn’t mean the current versions are more than mometized research projects. Yes that’s a problem if these are sold as full products, but that’s want they are. All users are currently testers for the AI companies. A lot of companies managed to get some of that sweet VC but that’s always been possible with the hype of that time. Now its just AI, gullible Investors have lost money since the invention of investing.
They apparently did a pretty large scale test to decide if a video performs better when the mouth ist open or closed. Open mouth performed so much better that they even retroactively photoshopped their old videos thumbnails to add a open mouth smile to them. That might also contribute to them appearing creepy since they only changed the mouth.
