Some of us are willing to pay a bit to try to build a better world.
Not really. Stubborn people building the world they want to live in regardless of short term profit or outside approval but only because it matters to them to live in that future world. That is what has really driven society forward.
You can't help others unless you know how to do the thing and you can't really know how unless you have done it yourself.
I'd hire basically any engineer who had run a home LN node over one who hadn't if I needed to hire for a larger node.
