basic synopsis is that more players are entering the stage. Some are using solid thorium, others are in molten salt.
MSRs are appearing to be picking up more allies.
Here is another good video review of current affairs with thorium from the same conference. The presenter from Terrestrial Power is mentioned in the first video.

Two things mentioned here before is that the russians and the indians had active thorium programs in the 1960’s & 70’s—but they abandoned them when the US did.
Also the graphite design for the Chernobyl nuclear plant was stolen from the USA before graphite problems had been straightened out.
