Because actually, it is, even though I can't imagine somebody actually creating uplifted sloths. Why the idea itself is fundamentally silly.
Unless of course, someone actually created them to be mobile sensors for the conditions in the jungles they live in. And the moss that grows in their hair could be a symbiotic organic computer matrix that not only records and transmits data, but releases necessary hormones into the sloth, or chemicals into the surrounding area. So these semi-mobile environmental laboratories/jungle guardians would still be creeping around, millenia after their creators are long gone, and...and...I think I need a lie down.
