What a badly written article. I hope he wasn’t paid much for it.

This may help:

To an increasing extent, the number of people needed in UK IT industries is declining, however there are still vacancies. This may show that there is still a greater, if reduced, demand than supply or perhaps an increasing reduction in requirement for personnel with the old skills and a reducing increase in the need for those with new skills. The reduction in the increase would be due to the increasing ability of personnel to provide new skills, but of course this would reduce their availability for the decreasingly available positions possibly leading to a static but still hungry market.

Clear?
