Teaching children to code, good or bad?

Barclays has been advertising life skills for young people as part of helping people gain new skills. The scheme is called 'Barclays Code Playground' which aims to teach children how to write in code. Their advert shows a child trying to making a dinosaur dance and say hello, by using a coding language. Children would pick up these new skills quickly and some could argue that children are our future so we need to prepare them for the wealth of technology that’s currently being developed. 

However, children be learning the basics of English and Maths before moving onto coding. Are we putting too much pressure on children to learn so much in their early years of education? We need to remember children leave school at 16 or 18 and we want them to love every minute of it while reaching their full potential.

The programme used to code on the video below is very simple and children with help would be able to use and understand what they're doing. I think it is a good idea as long as other subjects don't suffer as a result. Children are entering secondary school without basic English and Maths which is really worrying, should that be the focus or should it be the future?
