They, in fact still are. Only if you put the time and effort to know what goes inside, It's not fun in terms of learning, but interesting. Then it becomes fun after you really know what goes on.
Okay, I used the word "possible", but perhaps I should have used the word feasible. If the information exists then it's "possible" to learn it. Although given that the hardware companies no longer actually tell us everything that's going on in their hardware, you could make an argument for it not being possible.

Not with most of the terrible (i.e Lenovo, Wikipedia) information found online, It's never impossible but very unlikely.
