Python and Ruby are great languages to start with but definitely not the end goal (for anyone who really wants to gain a deep understanding). They make the transition to understanding lower level languages e.g. C a lot smoother.
I don’t think that analogy is accurate. Python and Ruby capture the essence of programming- they still require one to think logically and structure problems in precise computational language.
Yes, they do operate further from the underlying hardware- but as a beginner, this isn’t really important. Once you’ve grasped the basics, languages like C become a lot more accessible and you can better appreciate what the higher level languages do for you.
I guess it’s personal preference at the end of the day.
