If the world survives the Mayan doomsday, I would like to see some genuine musicianship brought to the art of playing the theremin. As it is, most of the interest seems to be from adolescent and post adolescent 'noise boys' with little or no sense of music or pitch.
The whole question of FX is a slippery slope. Most of the time they are used to mask a lack of skill rather than to enhance the music, but they are widely appreciated because they are relatively cheap to buy and they give the user the feeling that he or she is actually doing something. This is particularly true of loopers.
What the theremin world really needs are some genuinely engaging, original, melodic, short, simple compositions. Pieces people LIKE to hear, WANT to play, and CAN play. The aleatoric pieces that are regularly posted to YT and elsewhere by thereminists are unrepeatable one-shot deals, and cannot be performed a second time by anyone (not even by the composer).
There has been a recent spate of "serious" compositions for theremin but it is unlikely that they will survive their premieres or, in the case of CD recordings, that they will be picked up and "covered" by other theremin players. They are too esoteric and there are very few thereminists who could play them even if they wanted to. I am thinking here of compositions like the recent theremin concerto by Finnish composer Kalevi Aho, the UNIVERSE SYMPHONY #3 by Fazil Say, the recorded works of Barbara Buchholz, Dalit Warshaw, and others. As brilliant as these works may be, they are unlikely to set the world on fire - not even the Theremin World.
Fred, you're right. People tend to get upset about off-topic remarks because they disagree with whatever was said, not because whatever was said was off-topic.
