Coding will become very much in demand, not all will succeed in having mindset to accomplish.
Good fall back always to trades that will be required into the future, perhaps if they make small business easier to run it would encourage more down that route, needless to say still need qualifications which is sorely lacking.
Oh yes and we know that not all will make it. The good thing is that they all shine in proper maths and there are many other computer fields that they can enter. They can already make websites and games.
Just the basics, but they will learn as they go.
Oh yes, small businesses is what is going to save this country and here you also mentioned the "fall back" option. They will all receive small business management training and such in their second year. We run a 3 year project from Grade 8 to Grade 10. At the end of GRADE 10, they will do the Python exam and those that pass will walk into a job.
Sounds well mapped and orchestrated, now it is up to the the youth who are willing to put themselves out there!
Thankfully we have a few of those and many more are eager to start, so we will see, what we will see my friend.
