Edtech, it's failure or yet missing success
Arguably, YouTube (YT) is the best education technology platform on the internet, yet it is just a non-creative successor of the VHS/TV and not even CD(which had the menu, breaking the linearity of the frames). The bits are transmitted over switches and routers instead of a cartridge with a magnetic tape, improving the latency for the end-user and YT also has the recommendation system which is usually a hit-or-miss. YT has definitely the largest educational content to offer, though it can be difficult to find or even search for it. And it's lacks interactivity, has the comment system of 1990s. Khan Academy overcomes some of YT's deficits, but adds too much friction to the user interface and user experience and is a one-man show. Is there any innovation happening in this field, and what is your opinion on the future of this education technology?
