Mo Gawdat in Solve for Happy proposes an experiment he calls The Eraiser Test.
“Imagine a new technology that allows you to choose any past event you don’t like and simply erase it as if it never happened. Erase it from your memory and from the actual flow of time as well. The technology manages to pinpoint that exact event in the space-time continuum and uses a rubbery algorithm, written in just a few thousand lines of Python code, to wipe it clean. The technology also traces the effects of the event across the trail of time and automatically erases all of its consequences all the way up to the present moment.”
