I would slightly disagree, not to say that ain't no problems but there are less issues with them. First off, you do need a password manager; no human can remember all the different passwords to all the resources you access. With that in place, you need to pick one that meets your criteria - namely, to support passkey and hopefully on all platforms you use (MacOS, Linux, Web, Windows, whatever). After that is settled and you have your password manager on your windows, your mac , your browser and iPhone, life gets easier since you store them in your smart password manager. The icky feeling I have is still you have to "trust" someone (your smart password manager provider) not to f-up (tall order one might think) and keep you safe. That is a risk not everyone is willing to take. So, in my humble opinion, passkeys are not inherently bad; it's the implementation you choose that is important and worth a lot of your time to plan properly and educate your users.
