The majority of humans will almost always take the path of least resistance, whether it's cognition, work (physics definition), effort. LLMs are just another genie out of the bottle that will enable some certain subset of the population to use the least amount of energy to accomplish certain tasks, whether for good or bad.
Even if we put the original genie back in the bottle, someone else will copy/replicate/rediscover it. Take WhatsApp locked secret passphrase chats as an example - people (correctly) found that it would lead to enabling cheaters. Even if WhatsApp walked it back, someone else would create a new kind of app just for this particular functionality.
