RE: 2: I think I agree. There are lots of "CS" programs targeted towards high-school students which I have mixed feelings about. The goal shouldn't be to turn every student that walks through the door into a SWE (there's somewhat of a conflict of interest here considering most programs are sponsored by big tech companies who are desperate for talent – Microsoft does a lot in this space). Instead, I think it should serve a few roles: expose students to new opportunities (learn if you do want to be a SWE); give students the skills to understand that computers and algorithms are not magic (important from a public awareness perspective); and also to teach enough "deep" technical skills to prepare them for a world dominated by software (e.g., learning how to query databases, write small automations, etc.).

But I think most important is that intro courses need to serve as jumping off points (i.e., they should be INTRO courses). Give students a taste and let them decide if they like it and want to take another bite.
