In general demand for programmers has been growing over the long term. So if the baseline is an upward trend, these tools can have a demand-reducing effect and the overall demand can still be going up just at a lesser rate. Or it could be flat or go down - my point is that one thing reducing demand doesn't necessarily mean that demand is going down.
