| How do you decide which of the free resources are authorative? Maybe you learn some bad habits from that popular youtube video? * Case in point there is a popular ML guy on youtube who is also considered a bit of a hack. * When Khan was starting out some of his original videos were also critiqued when they were out of his area of expertise. * My friend learned Spanish from a teacher from Basque area. He has an intriguing accent now... * There are zillion Python videos on Youtube and many are not quite good. The problem was pointed out in 1970 Future Shock by https://en.wikipedia.org/wiki/Alvin_Toffler . It is much easier to spend time choosing an authoritative educational institution(online or offline) than individually choosing each teacher. You let the school do the curating for you. There will be bad teachers even at good schools but your meta cognitive load is lessened. PS I am a bit biased since I teach at various non-profit and profit institutions (I also stream on youtube but privately) |
