Doesn't that line of reasoning leave you in danger of being largely ignorant? There's a wonderful quote from Twain "History doesn't repeat itself but it often rhymes" there are two critical things I'd highlight in that quote - first off the contrast between repetition and rhyming is drawing attention to the fact that things are never exactly the same - there's just a gist of similarities - the second is that it often but doesn't always rhyme - this sure looks like a bubble but it might not be and it might be something entirely new. _That all said_ it's important to learn from history because there are clear echoes of history in events because we, people in general, don't change that fundamentally.
