They are usually ignored because they seem to be at least a decade away from any practical application, and kept being that decade away for at least the last entire decade. But if this changed, than yeah, people should stop ignoring it.
Their pace significantly accelerated since the original tweet where they showed a fully assembled pathfinder vehicle on the launch pad. Before that tweet I thought Blue Origin was way behind. Now they are at most a year away from having a successful rocket and two years away from a moon landing with their prototype MK1 moon lander. At the current pace it is not unthinkable that Artemis 3 and 5 could happen a year apart.
To be fair, they are working on a lot of the advanced problems before they get the basics. So they may be closer to a practical application than it looks.
But they didn't get the basics. Getting high up into space is much, much easier than reaching orbit. To the point it's a qualitatively different problem.
This is a good point. Not much is said about Blue Origin. Perhaps because they're overshadowed by SpaceX? But Bezos is launching rockets.
* Their New Glenn rocket is reusable and can launch 45 tons, focusing on the commercial satellite launch market. First launch in Spring of '25.
* New Shepard is more like a tourist transport, delivering passengers to the edge of space. They have completed 26 missions so far.
* They're working on Blue Moon, which is a lunar lander designed to be part of Nasa's Artemis program.
Here's a video of Bezos talking about (and showing) the first New Glenn rocket being prepared for launch.
