I mean the sport of Tour de France cycling disappeared for a decade, replaced by an identical-looking-but-fundamentally-different sport of competing to see who can cheat (dope) the best. It was probably not even possible to get into the TdF during that time period, without doping, there were so many people doing it.
It is entirely possible, that chess (as a professional competition) is not going to survive this, because it will turn out that with modern computing and communications technology, it is not possible to prevent cheating. Whoever wins the competition, will be the one who cheated the best. Chess will be replaced with an acting and subterfuge competition.
