How popular media portrays the employability of older software developers
I've worked with two types of older engineers:1) Ones who keep up their skills2) Ones who don'tThe former are a treasure trove of knowledge and skills, and provide substantially more value than anyone junior ever could. Going through so many computing eras gives a higher-level way of thinking about abstraction, or understanding computer architectures. They've hand-tweaked assembly, C, Java, and when they're now doing JavaScript or Python, they understand all the layers of metal underneath. They've gone through flow charts, structured, functional, object oriented, and all the variants there-of. They've written high-speed algorithms to draw lines with pixels, to ray trace, and are now coding GPGPUs.The latter are liabilities, bringing in 1980-era best-practices. They're working on some legacy BASIC or COBAL system from the seventies, and surprised they can't find a new job when that's upgraded and they're downsized.I've rarely seen #1 and #2 mix. They're very different crowds, and in very different types of companies.My own experience is that I need to devote about 20% of my time to keep up, if I'm doing it on an ongoing basis, or about 1-3 months every 2-5 years if I do occasional deep dives. Basically, I dive headlong into whatever is the newest, trendiest stack, and get a product out using that, deeply learning all the deep things behind it too. That's what works for me. YMMV.
