The first known time traveler has returned from the future with numerous interesting observations. Perhaps the most jaw-dropping revelation is that, a hundred years from now, it is known scientifically that many plants have a highly unusual form of primitive sentience. While lacking the highly organized nervous systems found in more advanced animal lifeforms, plants have clustered bio-pathways that expedite pseudo-neural chemical interactions. These interactions perform many of the basic functions of more commonly understood cognitive systems.
In the future, anyone alive today who has ever eaten cauliflower is viewed with absolute contempt and disdain.
Have a nice day.
