In the old days, a few motivated nerds could write a browser. Now all you can realistically do is take a browser engine and build some user interface around it. That what most “alternative browsers” do - tweaking or repackaging.
These days, a browser is like it’s own operating system with sandboxing, various Interfaces to periphery devices, hardware acceleration for GPU and all the bells and whistles taken for granted now.
I’d say that imagining it to be on a scale similar to working on the Linux Kernel is more right than wrong.
So we definitely very much want Firefox to survive, or it will be much worse than the Linux/Mac/Windows trilemma. Microsoft Edge is chromium under the hood too. Any many desktop “apps”.
I think about Reddit-style platforms being the centralized bulletin boards and forums of these days, and Lemmy is closest we have to a DIY kind of thing which is controlled by the community.
Back in the day only a sufficiently tech savvy person could set up and run a forum software. Now everyone can do it, and with the Fediverse it’s all nicely interconnected, interoperable and truly free and open.
In general the Fediverse is the best shot we got right now to get back to the non-corporate Internet of my childhood and youth, I really hope it will succeed. And succeeding does not mean that it must grow and outcompete the commercial offerings, I think success is if enough motivated and interesting people join and participate. Quality > quantity.
