Cape Town - The rich list of wealthy individuals indicates that technologists have continued to grow their wealth.
Bill Gates has, according to Forbes, regained his title of world's most wealthy individual this year with an estimated fortune of $76bn.
But the former chair of Microsoft continues to sell shares in the company, and it is likely that he will be passed by Steve Ballmer as the largest shareholder in the company.
Ballmer's wealth has climbed to $19.3bn since his departure as CEO, reflecting the overall trend for the top wealthy technologists who have collectively grown their assets by around 40%.
Second place belongs to Oracle CEO Larry Ellison, but at $48bn, he is way behind Gates.
