i personally dont have an issue, me and my friends mess with our teacher when he accidentally says that we have 9 planets or that Pluto is a planet, (he's a physics teacher), but i do think that if they're gonna change it they should also stop teaching that there are nine planets, my cousin who is in the 3rd grade just recently started learning the planets and they told him that pluto is a planet, if theyre gonna change it then they should teach it that way too
