BERNOULLI'S PRINCIPLE
I had a technical question for you Aeronautical Engineering guys. I was reading online somewhere some engineer was saying that the Bernoulli principle is theoretical as the air travels up the wing wouldn't it cause friction as well and push the wing down?

yes, there will be some friction, but it is negligible amount in front of the pressure region created.
there is a boundary layer formation on a solid surface moving in the fluid medium.
flow close to the surface is laminar,fluid (air) forms a skin on the surface of the wing,which reduces friction.
