I think our experiences aren't that different but our view of what juniors need probably does diverge. "Algorithmic or read-up-on-it technical or math" aren't the things I consider to be deeper thinking for programmers but instead are skills and methods that we'll always be continually having to add or hone. Deep thinking, which through my experience with others qualifies as hard due to the relative rarity in which I've seen them capable or willing to do, are much closer to the things you feel are brainlessly easy. That's not unusual since we often under-value the things that come easily to us by assuming that it comes easily to everyone. Learning how to _think_ about a problem, how to understand it at a fundamental abstract level and then build a mental and theoretical model needed to bring that vision to the point where implementation can occur is far harder than writing the code for the vast majority of people. I also used to think "this is obvious and easy for me so it must be for others as well" but time and again that's proven not to be the case. I learned to focus on making sure my people can think the right way so that at worst they can respond to surprise difficulties or crises on their own but the best hope is that they become better than I am. With the right people in the right environment, if I'm doing my job well I will make myself redundant or superfluous.
