At the end of the video he warns of the dangers of "dogma". He looks really nervous and impatient in this talk. He seems afraid that it won't be well received. If so, it is interesting to note that this is what dogma in fact leads to... repression of new ideas, fear of free thinkers and the stagnation of true scientific progress. It means guys like Bret Victor will feel awkward giving a talk that questions the status quo. "Breakthroughs" do not happen when we are all surrounded by impenetrable walls of dogma. I wonder if we today could even recognize a true breakthrough in computing if we saw one. The only ones I see are from the era Bret is talking about. What happens when those are forgotten? My friends, there is a simple thing I learned in another discpline outside of computing where I witnessed doing what others thought impossible: the power of irreverance. This is where true innovation comes from. It means not only questioning whether you know what you are doing, but questioning whether others do. That frees you up to work on what you want to work on, even when it is in a different direction than everyone else. That is where innovation comes from: irreverance.
