Developers are notorious neophiles who love adopting new technologies and designs. There is a natural bias between interest in working in emerging sectors and a general interest in novelty.
Technology as an industry also emphasises change and novelty as part of its identity with concepts like “disruption” and “innovation” being fundamental to the self-identity of the sector.
I also believe that developers are perversely incentivised to value the new over the established.
If you choose to learn an emerging language you have less history to deal with.
If you learn Java you have access to lambdas but you also have to deal with a decades worth of code that was written before lambdas were available. You’ll have to learn about interfaces, with and without implementations; inner classes; anonymous classes; dependency injection and inheritance.
If you choose to learn an emerging technology then chances are you won’t be told to RTFM as it won’t have been written yet.
Instead you’ll have the chance to interact with the technologies creators. If you make a mistake then it will be a learning experience not just for you but for the community as a whole. You’ll be united in your discovery and collaborators instead of an ignorant johnny-come-lately.
And if you learn emerging technologies you will find that conferences are eager to offer you a chance to talk about your experience. Employers will value your knowledge more than the people who added another year of experience with C#.
In every way you will find life easier and more enjoyable if you focus on emerging technology.
Falling out of love
Programmers are often like ardent lovers, in the first flush of their crush they see their new discovery as the answer to all their problems. They are evangelists and poets for their new discovery.
But over time familiarity replaces enchantment and soon we are all too aware of the flaws of tools and take for granted their utility.
When our sense of possibility of what we can do with our tools is exceeded by our understanding of the constraints they have, we start to look elsewhere.
A mature legacy
Legacy is a funny word in technology. As has already been observed most of the time people are delighted to receive a legacy and the word generally has positive conotations.
For developers though the term is loaded with fear as what we are inheriting in the form of a legacy codebase is not a valuable treasure that is being handed down for safekeeping, to be enhanced and handed on to the next generation of stewards.
Instead the legacy codebase is seen as troublesome, an unwanted timebomb that is to be kept in some kind of running order and passed off to someone else as soon as possible.
Maintainers of legacy codebases are also unvalued by organisations. They are often seen as less skilled and less important than developers creating new systems. After all what they are doing is simply keeping a successful system running, they don’t need to use much imagination and they are dealing with solved problems.
Maintaining a legacy codebase often means being overlooked for promotion, pay rises or new opportunities.
In fact this view extends beyond developers, organisations do not tend to value their legacy codebases either. Product managers are equally incentivised to value the new over the old. If they add features to an existing system they are seen as less imaginative than those who create brand new systems or approaches to existing problems.
I have seen product managers deliberately sabotage legacy products so that the performance of the new solution looks better. Management often fails to look at the absolute performance of new system, just the relative numbers. People exploit that tendancy ruthlessly.
Love the new
There are more examples, however they might be better suited for dedicated blog posts in their own right. Overall though I hope I’ve illustrated that how as a profession we are encouraging people to jump on every bandwagon that is passing by.
I want to try and avoid passing a moral judgement on this. I too am a neophile, I too love novelty and would prefer to do something that I haven’t done before over perfecting my skills in a domain I know.
I just want to try and highlight the issue and move it from our unconscious to our conscious minds. Is this what we want for ourselves?
Should we rewarding maintainers of the software that pays our wages less than “rockstars” building prototypes?
Should we value simplification of our existing tools over maintaining backwards compatibility?
These are all inherently cultural issues, not technical ones. Currently we have a culture of novelty and literal innovation. I’m not sure how well it is serving us.
