> I'm not living on a boat, and I'm not working on a Raspberry Pi. Why rewrite the software I use into something more lightweight when I can just use the software without consequence now, and save all that pain?
There is a very real trend of people in the computerspace who are applying the "questions" that climate change and working towards a more sustainable world ask us: much like in the physical world, doing always more is a mistake and if we can do what we need to do with fewer resources, then changing our tools to reach this state is a worthy goal in itself. Not only because we should reduce our usage of resources and energy and make sure our tools last longer than the single-digit years they usually do in computerland, but also because if/when TheCollapse (TM) finally comes we won't have access to the latest and shiniest tech anymore so we'll have to make do with what we come up with, and that's going to be old computers and phones lying around unused.
So as always it's a question of priorities: if you don't consider resources usage and climate change as an important enough issue, doing what they're doing will always remain in the domain of hobbyists enjoying their little fun, just like those people who build the most insane programs with fewer characters than are in this very comment.
