If you could un-invent something, what would it be?

To tell you the truth I really don’t want anything to be uninvented because they all have contributed in the progress of society, however I want AI to be uninvented since from its invention a new class bad habits have developed, of those one is less use of human brain…………
We are overly depended on AI for our daily like writing assignments in college, email to business partners or creating videos, in all these scenarios where the hell are we using our own labour nowhere and it is like we are regressing back to old times…………….
So yes if I got this option I would definitely strike the lightning on AI……………..
