My version of this was a 10-week discrete RF circuits course in graduate school. We had to build a fully functional GHz transceiver out of small FR4 PCBs (< quarter wavelength) and throw-away leaded BJT transistors. Neither were suitable for GHz circuits, so the course was hard by design. I learned so much and developed an intuition for electromagnetics that I still carry 20 years later.
From my experience on this, the single biggest determining factor on one's opinion is whether you have kids (I have elementary-age kids). We have to work like mad to limit screens, but it is an uphill battle. Their schools use them, their music teachers use them, their after-school tutoring (Kumon) uses them, and so on.
I have a vivid memory of my son's 6th birthday. At his school, kids would sit in a circle and get to ask questions to the birthday kid. One of the questions he got was: "Who is your favorite Youtuber?" His heart sank when he said he wasn't allowed to watch it, and the other kids were kind of shocked.
I second that. 3b1b is fantastic for developing a more intuitive understanding of mathematics. In my experience, having that intuition makes all the difference.
