I agree with what you say.

I went to a British Secondary School, and am just about to leave Sixth Form - I took computer science at both levels.

The trouble is - again, at both levels - there are few teachers who understand the topic. Scratch and the like are easy to learn for more or less anyone, and teachers can teach it easily. I know that in some cases CS teachers are IT teachers who took on the extra subject.

With like Python, unless the teacher has actually written a decent amount of it then they're going to struggle to teach it well. If they've never properly programmed, they will also struggle to point out that "Twitter has an API that you may want to use to analyse tweet contents", for instance.

I'd just like to reiterate that I am not disagreeing with you, I would very much love a curriculum change. I just think that the lack of qualified teachers needs to be addressed as well.
