You are obviously with them in the wrong room....

Once you know them for who/what they are, and you learn to be comfortable enough with not following them closely, or not knowing what the hip thing is right now, then you can learn to let go of that (almost) insatiable need to keep up. Let them have the room - and the mental energy it requires.

I'm not entirely convinced this is the argument.

From what I've read so far, it seems that ESA was uncomfortable with the possibility of a collision to a degree that SpaceX could possibly be quite comfortable with - ESA wants > 1km distance, whereas SpaceX might be comfortable with much closer - they are quite different constellations.

Who has the right to dictate who has priority / which criteria is the right one?

I'm going to assume that the cost of ESA's satellite is much greater than SpaceX's StarLink module so obviously they have much more of an interest in preserving full functionality - BUT avoiding collisions is in everybody's best interests. Who is going to use their fuel? Who has right of way, and to what terms?

Could be "improved"

That made me wonder about what would happen if google started grouping concepts (eg words for grandmother in other languages will almost certainly give you differing results) rather than words...

Possibly (probably) the cognitive load on people might lead to bad A/B test results, but it would be a curious thing to explore - cultural bias would get a bit of a beating I'd imagine.

It always comes in slightly to the side of the barge and as part of the landing burn it does a final sideways correction. I believe it was for this kind of situation - or one where the final burn doesn't even happen.

Didn't google earth have exactly this in the early days? I can't remember exact details, but pretty sure it was an easter egg - ctrl + alt + a would launch it.

"The non-powered vest offers protection and support against fatigue and injury by reducing the stress and strain"

Would love to see how this works and maintains an adequate range of motion so as to not get in the way. Seems like it adds rigidity so that the weight is shared by the exoskeleton.

I believe that comment is more or less based on the shuttle landing and/or the soyuz capsules (eg parachutes) - but as far as I can tell, SpaceX is the only one currently capable (and using) propulsive landing on earth - so essentially they've already leapfrogged the grey zone to a large extent.

Makes me wonder whether testing a propulsive landing on an airborne drone barge is feasible? A blimp with a well-insulated large pad on the top - though I'm not sure how you'd effectively anchor it in the air - probably a active propulsion system as well.

Except for things like volcanoes and earthquakes... Though grantedly that is a different kind of excitement.

You're still subject to much the same kind of media merry-go-round, and subjectively is probably not even that far away.

I would say on the whole, yes - that is actually true. Now you only need one "smart" person to program up the machinery, whereas in the past you did need multiple skilled craftsmen in a variety of roles - not exactly apples vs apples, but I think that one of the unfortunate side effects of too much specialization is a lack of a broad knowledge base that lets you apply skills from one field in a different area.

The way I've come to see it is "The less you know about a subject, the less you think you don't know."

In other words, you have no solid grasp on the field and so cannot make an effective guess at your ability in the field - so go for middle of the road and that's possibly your best statistical guess...

I'm pretty sure the implication is that the big corporates don't care a hoot about open source, the ethics or the model - they'll just take it, the cheaper the better.

The principle and supposed ethic is to share and have some reciprocity - the reality is somewhat different. And we all suffer. Tragedy of the commons, I guess...
