The same thing happens to programming positions.
But I think the good news is missing from this article—IT jobs are, overall, sticking around or increasing in number. (According to the Bureau of Labor Statistics, the jobs are growing “faster than average for all occupations”). You do have to keep updating your skill set, but it’s not like manufacturing, where efficiencies eliminate jobs altogether or move them to completely different sectors. And there is that ageism to worry about, and uncertainty.
I’m personally more worried about some of the other remaining white-collar office jobs, like the accountants, paralegals, HR, various banking positions, etc.
