iFixit says the Switch 2 is even harder to repair than the original

This is a most excellent place for technology news and articles.
People buying the console for the games that are on that console, not generations before, are 100% fine.
Beside, it's not something you have to fiddle with to get it work. Either a patch come, or you're on your own.
If by "Generations" you mean the literal previous generation that was advertised as backwards compatible and where many of the games won't receive specific patches precisely because running natively and better was one of the key features of the new console... Sure, I guess.
