Look... the post that said its always been a planet to us humans is wrong. Its been recognized as a planet for a couple generations.
Second... this is how science works folks! Thre was a time when "life force" was the underlying thing that make living things live. Dna was not recognized or known (in term of its genetic function) past two generations ago. Physics was a "dead science" at the turn of the 19th to the 20th century. The textbook I have from 10 years ago are largely outdated and in some cases incorrect in their assumptions. One book I have says enzymes are proteins. Now there are other macrobiologicals that are seen as having enzymatic activity.
While there are some potential issues with the "cleared its orbit" statement, if this helps better organize the systematic nomenclature and organization (which is a hallmark of all areas of science) then fine. Stick around long enough. It'll probably change again sometime when more knowledge is gained.
And, I hate to say it, but I R E A L L Y doubt it'll screw my kid up to have to explain that the classification of planets now excludes pluto, or relegates it to a lower class.
Again, if anything, this is the way dynamic science works. Or what a bunch of bored astronomers do for gits and shiggles.
