This is part of the web truths series of posts. A series where we look at true sounding statements that we keep using to have endless discussions instead of moving on. Today I want to tackle the issue of the web not moving fast enough for people and clinging on to seemingly terrible ideas from the past.
The web is broken and backwards compatibility is holding us back
This is the counter-argument to the one I discussed in the last post. Much like the exaggurated praise for the web and its distributed nature it has been around for as long as I can remember online discussions.
There is a problem with this though: as Calvin said it, the problem with the future is that it always turns into the present.
So, whenever we embrace new and bleeding edge technology and damn the consequences we create debt. Often arguments against backwards compatibility stem from actions like these. Some standards we have to keep adding to browsers have been rash decisions or based on a need of one player in the W3C at the time.
Breaking changes in any new version of software aren’t ever fun for users and maintainers. This gets worse with how popular your software becomes and how many people use it. And I’d argue that the web is the most used piece of software out there.
Back in the day the argument against the web stack was always Flash. It seemed to be the right thing to use. There was 99% coverage in browsers. It had far advanced tooling in comparison to Firebug (RIP). And there was a sort of built-in code protection. People couldn’t look at and steal your code without jumping any barriers.
Turns out, Flash wasn’t the amazing platform these arguments made it out to be. In the Flash Games Post Mortem keynote at GDC. John Cooney of Kongegrate talks about the story of Indie gaming and Flash.
I love this talk. It shows that Flash and Web developers weren’t that different. Except Flash developers were more pragmatic about wanting to make money. And they had less delusions about their code lasting forever but knew that they had a short window of opportunity.
And this is what this argument boils down to. When it comes to betting on the web, there’s a lot of good faith and wanting to create something lasting involved. If that is your thing it will make you more understanding for the failures of the web as a software platform. And it makes backwards compatibility a no-brainer as this is what ensures the longevity of the web. When Flash changed and the support from the one company that owned it faded, a lot of developers felt forgotten. We now have the problem that a lot of creativity and a lot of work will go away as the platform to execute it is gone. Backwards compatibility ensures that isn’t the case.
If your thing is to release something quick, make some money and know it will go away, the web isn’t as interesting. Even worse, those defending it can come across as evangelical or condescending. But there is nothing wrong with what you want to do. A lot of innovation stems from this approach, and the web can learn from its successes and failures. Much like HTML5 learned a lot from Flash. But that doesn’t mean your approach is better or that the web is broken – it just doesn’t fit your goals. Without the web, Flash wouldn’t have happened the way it has either. Air proved that. The distribution model of the web works. And you can benefit from that without having to replace it.
But all in all, the backwards compatibility of the web is what made it survive all the other platforms set out to replace it. And there will not be a time where we need to run the web in emulators because of it. That is what makes the argument of the web as broken and backwards compatibility holding us back invalid. Of course we can do better, but are we also 100% sure that what we think is amazing now really stands the test of time?
There are more pressing matters to consider:
- How can we ensure that despite backwards compatibility we get people to upgrade their environments? Seeing that a malware targeted at Windows XP is a huge success in 2017 is more than worrying.
- How can we enhance older solutions to become better without breaking them? Chrome’s passive Event Listener extension to addEventListener seems to break backwards compatibility . Arrow functions are arguably only syntactic sugar (despite fixing “this”) but will always be just a syntax error for older browsers.
- How can we make developers embrace newer solutions to old problems that have less side effects? It seems there is a certain point where we stop caring to keep up-to-date and use whatever worked in the past instead.
- How can we make newer developers embrace the idea of the web as a platform without overloading them with borderline evangelical and philosophical messages? How can we make the web speak for itself?
