It's significantly diverging primarily because of the laws of physics. Even "perfect" optics wouldn't help because you can't simultaneously have a small aperture and a low-divergence beam. And I'm acutely aware that increasing its divergence only exacerbates the problem, that's why I concluded some time ago that it's a dumb thing to do.

And what are people in space thinking about?

If they were closer to Mars, for example (dug into Phobos?), they'd be able to make real time control decisions for the martian roving vehicles, vastly improving their utilization. Speed of light is horrible for efficient operation of such devices. Some progressive Martian mission designs anticipate this scenario.

I sincerely doubt that Space X would create science only missions - like sending probes to Mars or the outer reaches of the Solar System.

No, but they could enable them with their cheap technology. Think of how cheaper the MSL rover could be if if were launched by a Falcon Heavy. All that weight-shedding typical for aerospace can't possibly be cheap. But we won't have any chance to substantially get rid of it until we get cheaper launches. (New Horizons probably could have been much more heavyweight, too, if FH had been available at that time.)

Dead? No excuse for laying off work.
