Wheel comes to mind immediately, given the consequences, it seems wild.

Worst, probably gunpowder, even though some famous countries in the world seem to really love it, even philosophically love it. Well, that's probably because they missed a chapter in History, either that or they want very hard to miss the aftermaths of what they love?

Best-The Internet

Worst - Social Media, Lies about Political stuff including all political parties

[Avicenna]

Writing would have to be the best.

Worst? Our destructive weapons of war.

[RebelinSteel]

Writing for best

Gunpowder / explosives.

I don’t think it covers tangible but if it did, the worst is religion.

[DrPepper12]

Agreed on religion. The WORST invention EVER!!!

The wheel.
