Kind of true, when one wants to be seen as "Developer in Tech X" and that is only how they sell themselves to companies selling software solutions.
However there is also the path of understanding business domains, brushing up soft skills and embrace being polyglot across multiple stacks, delivering working solutions for companies that couldn't care one second what their IT cost center runs on, as long as they stay in business selling socks or whatever they actually care about.
Independent consultants are the first to get cut when the economy goes bad. Companies aren’t looking for “Enterprise Architects” and “Digital Transformation Consultants” when they are just trying to keep the lights on.
No, you can’t be 45 years old (I’m 46) and say I understand the business domain and I can give you a really cool VB6 Active X control to solve your problem that only works in IE6 on a Windows XP VM.
Yes, if the CTO doesn’t care that he is using somewhat modern technology he should be fired for incompetence. He’s going to find that he has a hard time recruiting developers who know how to write FORTRAN for a Stratus VOS mainframe. Yes I’m that old. Been there done that.
Saying you know the business domain but not keeping up with technology is just an excuse that people make and then scream ageism the minute no one will hire them because their idea of cutting edge technology is ASP.Net WebForms or Enterprise Java Beans.
Yes, my current position is a technical consultant working remotely for Big Tech who has to understand business problems and not just know how to reverse a binary tree on a whiteboard. But, if push came to shove and a meteor struck all of their data centers world wide, I could put my resume out their and get a job with a tech stack that is at the right point on the hype curve.
I currently develop for mainframes and I can say they are still very relevant today in multiple industries. For my own company, we get a lot more bang for our buck than if we were constantly worried about the hype cycles.
>if the CTO doesn’t care that he is using somewhat modern technology he should be fired for incompetence
A ridiculous statement. The last concern of the CTO should be "are we using the latest tech for the sake of having the latest tech". Their concerns should be about cost, what the business actually needs, and what the future will entail. Finding new developers isn't that difficult, even for something like mainframes which most college grads today are totally unfamiliar with.
Your point about being more easily hireable by staying up to date with the current hype is true and valid. However the CTO doesn't have the same concerns as you. This is the important difference.
Tell that to all the states struggling to get unemployment benefits out because they can’t find enough COBOL programmers to keep their systems from melting....
Well, if that VB 6 is what keeps business running they will be more than happy to pay for it.
Also not working alone helps to sort out the issues when cutting costs arrives.
Finally I am not saying not to learn, rather people should focus on their business value as a whole package, and not being "Expert on Technology X, Y, Z".
I am about the same age, apparently it was worked so far.
It’s about optionality. If I either want or need to change jobs. I would much rather call recruiters and say I know the latest .Net Core/EF Core/ASP.Net Core than saying my only experience is with .Net Framework (which is in permanent maintenance mode) and I can deploy to IIS on Windows (even Azure hosts more Linux VMs than Windows VMs).
Especially seeing that when working as a Corp Dev, salary compression and inversion are real and the best way to keep your salary at market value is by job hopping.
