Like, it's not hard to verify Bernoulli's principle on your own...
Comparing the modern plane's wings, with plane's wings at earliest aeronautics history is certainly easy for everyone.
Thanks to internet era that makes anyone as if had a huge library. Before internet era, nearly all students probably didn't know about flat wings on planes at earliest era of aeronautics.
But I already told you that old plane wings don't contradict Bernoulli's principle... It's simply that the usual explanation of how lift works is not very adequate. Again, it's not that older plane wings contradicted Bernoulli. The way these wings worked was that when the wings were slightly tilted upwards, an area of lower pressure was created right above the top of the wing, while the bottom of the wing pushed slightly downwards on the air incident on them. This is similar to the way modern airplanes work (their wings are always installed at an angle to create the effect I described), and the airfoil shape is such that it both maximizes that effect as well as minimizing drag and stress on the wings. Bernoulli's principle does have something to do with all this, but the way it comes into play is more complex. The bottom line is, air does flow faster at the top of the wing, but it isn't just because of the shape of the airfoil, but more because of the slight tilt of the wing.
So the way it works is not according to the naive Bernoulli's principle explanation which only mentions the shape of the airfoil that is sometimes offered, and you are right that the lift is not created by the shape of the wing, and that the same can happen with different shapes of wings. I mean, fighter jets can often fly upside down, which according to the naive explanation wouldn't be possible. But the fact that Bernoulli's principle shouldn't be applied in that naive way to explain the phenomenon without further elaboration doesn't mean that it is wrong. Bernoulli's principle simply states that when you have an increase in the speed of the flow of a fluid, you have a decrease in the static pressure of that fluid. There is the simple Bernoulli equation that we learn at school which only applies to incompressible fluids like liquids, and there is also a more general one that also applies to gasses in some cases, but its action isn't as simple as that.
