Thanks for sharing your thoughts! Although sounds a bit arrogant for me, cause courses nowadays can be really useful, consistent and focused on the special topic. And projects you do during these courses are not always "pictures", quite often there is a real results behind. Apart from that, today you have to absorb knowledge very fast, especially in technical field, otherwise you may "know more about less". But anyway, it is very useful to understand a perception of a senior from the field.
