This sounds a little rose tinted to me. I personally think for simpler tasks, much more information is available these days compared to older times. There's many resources on how to grow a potato (and other things) on the Internet.

For other tasks, some things have simply become a lot more complicated to work on. Electronics were a lot simpler in older times, for instance; swapping out a surface mount quad flat package will require a lot more "finesse" than swapping out a 1960s capacitor. Cars too have gotten more electronics and software. Despite this, there are definitely still people that have the skills to repair modern electronics and cars. (I will say that these types are often hampered by manufacturers that seem hostile to the idea of users being able to practically repair devices, hence the "right to repair" movement being a thing these days.)
