Older engineers rock


Are old engineers obsolete dinosaurs?

Plenty of anecdotal evidence suggests that employers prefer younger engineers over one who is 50 or older. But a new study suggests the peril of that position.

In “Is Programming Knowledge Related to Age?”, a recent paper by Patrick Morrison and Emerson Murphy-Hill, the authors ran a big-data experiment to see if aging developers have trouble with the latest technology.

The experiment is somewhat crudely-crafted (perhaps the study's authors are graybeards). By tracking responses to questions on Stack Overflow they correlate the site's “reputation” statistics against age. Interestingly the vast majority of participants on that site are youngsters, clustered around 29.

Turns out, old folks rock.

Reputation on Stack Overflow peaks around age 50 and does show a sharp decline by 70. Even at that not-so-advanced point in life, the average is about that of a thirty-year old and is much higher than someone five years younger. While young folks show little standard deviation, oldsters reputation varies wildly, with plenty of data points well above the average (and some well below).

By noting the kinds of questions Stack Overflow participants respond to, the researchers determined that older developers have a significantly wider range of skills than young people. That levels out around age 50 and enters only a modest decline later in life. Again, the standard deviation is huge.

How much of that knowledge is about new technologies? Here the results are less clear, though the authors believe their results show age does not confine one to the tech of yesteryear.

There are some real problems with the study. No raw data is presented; it's all expressed in graphs and reduced summaries. But it sure appears that there are only a handful of people studied over age 45. And the experiment took place within the narrow confines of Stack Overflow, and using reputation as a proxy for knowledge, both of which are somewhat suspect as determining anything about the developer population as a whole.

But as one who will achieve the ripe age of 0x3c shortly, the results are encouraging. I intend to forget any data to the contrary, ignore the shorts caused by my shaking hands soldering SMT components, and continue to design MCUs with vacuum tubes.

  1. Jack, I still have some catching up to do at only 0x33, but I really think that us oldies have a huge advantage.

    When we look at a new technology, we have a framework of experience and knowledge to help understand it.

    The young-uns, however just see new

  2. There are both younger and older engineers whom I would never hire and others I would really like to hire if I was ever in the position. I'd test and ask questions to all of them the same way. I'm also 0x33 and am looking at going for ARM certification a

  3. I'm a middle age engineer. My observation of many skills in life is that people who are always hungry to learn and hesitant to become proud and stop growing are the ones that become great. A great many of us seem to decide that our skillset is “good enou

  4. Well I'm 0x3D and still going and don't intend stopping now.I'm not working at he cutting edge but still designing relevant products for export around PICs and AVR32 and writing in C.Best of all I now have clients not employers!

  5. 0x3b year old here. Picked up a masters in ECE five years ago with a 3.9/4 GPA so seem to be able to handle new technologies.

    But the headwind in the job market is overwhelming. I don't even get a phone interview when applying for jobs that could be writt

  6. From what I've seen, a lot of those who lose the hunger to learn, somehow make it into management.

    As others have said, I've worked with good young and old engineers, and bad young and old engineers. Attitude often is key.

  7. I guess I will be the youngster at 0x31! I earned my two year degree in 1984 and worked to earn the title of Engineer at several places. After a six year stretch out of technology I got back in to the field in 2008. I've already made it back to an engineer

  8. “But as one who will achieve the ripe age of 0x3c shortly” reminds me of the old saying “there are 10 kinds of people, those who understand binary and those that don't”.

  10. To me, this brings up a great cultural issue that I have been aware of lately. Here, anyone with about 5 years of experience wants to get into management. So, we seldom come across older technocrats who still know the chops. There are few career paths beyo
