So far I saw half of it, all valid points from him, this seems to result from a thorough mind work.
I support this mind set, however there is one important point he may address later on in his speech: the value of consensus. Modern science results itself from the interferences of a number of socio-cultural fields, from public health institutions to for-profit business, to name one interaction.
Hence starting with that freedom of mind he proposes his a good starting point, a good scientist will then try himself to bridge the gap
toward its colleagues. Clashing is hardly constructive apart from proving everybody else to be idiots for the centuries to come; scientifically of little interest.
The risk indeed is to take the starting freedom as granted and lose oneself into the shapeless realm of the forgotten self
