It's a shortcoming each of us will have, if we're so lucky as to live that long.

But we don't know anything about the long term effect of 0g on human fetuses, which live in a very different environment than the humans we have tested. They live in an environment that combines fluid immersion and surface support, with buoyancy playing a major role -- which could (or could not -- absence of evidence etc) seriously change the importance of gravity for development.

I'd be more concerned about the impact of zero and low gravity on newborns than fetuses.

Yeah, the general approach to get support has been to be famous or to marry a Google employee, but the churn rate on Google employees is at the point that the latter is unsustainable.

I fly direct from London to Vegas occasionally. The upside is that going through immigration is trivial -- of 270 people on a flight, 265 go to the "foreign passports" line. The downside is the 15 minute wait after getting to the gate for the police to come and arrest the people who were fist fighting in the aisle.

I think there's another set of questions here -- why is "blue-green family" a thing in your mind, rather than "blue-yellow family"? Is there a "red-blue family"? "Orange-blue"?

For some people's language usage, blue and green are adjacent colors, and thus defining a point that divides them is perfectly fine.

For other people, these are not adjacent -- for some people, there's a single color (aqua? turquoise?) between them, and green and turquoise are adjacent colors, as are turquoise and blue, and it's reasonable to ask about a dividing point between those adjacent pairs.

For those who don't use language this way -- do you consider red and blue adjacent, or do you consider purple (violet?) a necessary intermediate? Are you comfortable defining a point between red and blue, or are you instead comfortable defining a point between red and purple, and a point between purple and blue?

And for all I know, there are people for whom blue and green (or blue and red) have a distance greater than one, or greater than two...

This is… not how humans work? If you have the time and energy to learn ten things, and then spend time babysitting a random number generator to produce evidence of 10 more units of work, you’re paying an opportunity cost compared to someone who spends the time learning an eleventh thing. You can argue who has more short term value to a company… but who is the wiser person after a thirty year career?
