I dont think 2020 will have any negative impact on the community.
No comps != no cubers
A lot of these new cubers from quarantine (myself included)
Have never been to a comp, therefore arent missing them yet, as they have never experienced them. Thats how i feel at least.
With needing several robots, you might be thinking a bit too small. Nobody ever specified how many cube slots it should have, you could have one robot scramble multiple cubes at once. Financial/design aspect does come into play here tho.
also a bit more on topic, i recently had a conversation about this with a friend who is a delegate, and they said that there are no plans on removing clock. its a controversial event, but unlike magic its an actual puzzle that can be scrambled.
