I think this is really exciting. A year ago, I was looking for something exactly like this - a formal course in Computer Science, with access to top mentors, which could fill in the theory gaps in my mostly-self-taught background, and which I could do in my own time whilst juggling looking after my young kids. Back then, the options were either MOOCs (free but no consistent mentorship available), remote bootcamps like Hack Reactor (expensive, limited syllabus), or audit a course at a local uni (also expensive in the US, limited access to resources, have to jump through annoying course prereq hoops). Or, of course, commit to a full-time degree, complete with the long-timeline application process, the expense and the relocation hurdles. More recently, several online CS Masters degrees have been made available but at eye-watering prices. (UC Berkeley's Data Science MSc weighs in at over $60k!)
This fills the need perfectly for mid-career types who want an affordable option that fits in alongside their work and family life. I think there's an enormous unmet demand here, particularly in an era where professionals need to keep retraining throughout their careers in order to stay relevant. I really hope that this opens the floodgates and other top institutions will follow suit.
