There was a lot of positivity toward blockchain tech on whole. My favourite was Dr. Dan McGillivray (Associate, Yeates School of Graduate Studies)[0] dept discussing Toronto's [and Brooklyn's] microgrid projects.
I really enjoyed Suhail's[1] talk. He came from engineering as I recall, so as a lead he was very in tune with the technicals. He was also very cautious. I don't think he was too down on blockchain tech as a potential solution for certain problems (otherwise why bother experimenting), but he was very clear about their sentiment toward existing cryptocurrencies. However, I'm starting to think maybe he was referring more to Bitcoin because of the selection of his audience -- which was largely bankers and other corporate non-technicals receiving an introduction to new tech.
But overall the sentiment seemed to lean toward positivity, even if it was not directed at a singular implementation.
