Some of our ideas are exploitation in nature and other ideas are exploration. Exploitative ideas represent update of old ideas while exploration take a creative aspects.
I asked this question because of the word of (maybe) so, your second part of your answer is very interesting regard the reality not the originality of an idea
Some new ideas were evolved from old ideas through vertical thinking. Some new ideas were generated through other stimuli, inspiration or lateral thinking.
Logically, people identify a new term because the old one. However, the new ideas may be and may be not an update of the old ideas, as it is mentioned by Dr. Tariq. I think, besides updating, the new ones may also complement, deputize, or substitute the old versions.
My bet is that almost all ideas are the result of twisting something from the past into a new form. Maybe a new perspective on an old idea, or a clever way to implement what you notice in the natural world (which is arguably too and "old idea").
Innovative thinking involves not feeling obliged to be limited to the old way of understanding things, in my opinion. These new ideas rarely come from nothing, it seems to me.
I feel new ideas are often a novel way of looking at old information. As such they are not an update of an old idea. However having said that, sometimes they are reminiscent of very old ideas already expounded by some of the wisdom traditions. I believe the atom was already mentioned in the Vedas.
