C++ would be absurd for systems admin and operations scripting, however. Other langauges do all those things and also excel in the operations/admin/batch processing realm - Python, Perl, Ruby
the current craze of using javascript for other than embedded in web page is just passing fad, it does not have the mature libraries of other languages to be general purpose. No one is going to write Linux configuration/admin systems in javascript, nor making general purpose cron jobs. Python and Perl and Ruby excel at that sort of thing, on the other hand.
python has threads; no one cares about your definition of "correct print statement" since it always could print; Python has libraries for specific data processing that needs to be done very quickly, but the truth is 90% of a program won't be dedicated to that
What Python does have that makes it good candidate are mature libraries for all the use cases mentioned (web, server scripting, client gui, etc.) So does Perl 5, and to lesser extent Ruby has good libraries though not nearly as encompassing as either Perl 5 or Python
A choice for a general purpose language for server scripting, web, client gui, non-web server apps,etc. should have mature set of libraries and frameworks for all those things. Most of the people here are posting their favorite or pet language rather than anything that has that property. Yes, Python has the libraries for all those uses, Perl 5 even moreso. Ruby does to lesser extent than those two.
but we only very recently had any hard data at all to deal with the first two terms of Drake equation, the six decades were largely just arm waving and bullshit
nonsense, those "smarter" people had no hard data, kepler is finally the beginnings of some data to even gauge the first couple terms of the Fermi Paradox problem
Mars doesn't have internal dynamo because it it tiny, it cooled off already. Earth sized rocky planets with similar composition take billions of years to cool, and so will have magnetic field.
I say your intuition is off, from Kepler's observations (and realizing it can only see transits of about 2 percent of stars because most orbit orientation don't allow it), there should be hundreds of millions of planets with life but spaced 100 light years apart. However, life usually is single celled, as we know from most of earth's history. Intelligent life, existing at the same time as intelligent life? spacing gets greater, 1000 light years maybe?
you make unwarranted assumption on how close the "solar systems" are together. if there is one (with habitable planet) every 50 light years your idea falls apart.
our radio and television transmissions to date are too weak for our own tech to detect at 10 light years. and we're mostly using fiber and other lines instead of sattelites for comm as time goes on. what if they are a thousand years ahead of us, we can't detect a modulated beam of neutrinos or gravitons for example.
but four light years to the nearest star and 14,600+ stars within 100 light years. And by the way, we know EXACTLY where to point lasers (not foolish radio SETI) for stars at that distance to be detected.
nuclear pulse drives need special fuel that may be quite hard to come by, a working geodynamo in a planet's core to concentrate a particular ore body is needed.
pressure builds until bullet leaves the barrel, otherwise you've either undercharged or overcharged the round. the barrel has to be able to take the pressure same as the brass which is supported by chamber. when the bullet leaves the pressure drops. the bullet spins faster and faster as it travels through a rifled barrel, rifling only at the beginning would leave insufficient RPM for stabilization; the last ten percent of the barrel has the most important rifling.

I think that's the answer to the Fermi paradox
feeding and clothing everyone is not a goal any nation has or ever had.
space exploration, however, is.

laser pulses are easy to detect. radio SETI is silly
no problem, suppose the human were suspended in a tank of water
so let's do the sensible thing and ban prostitutes just like we quite sensibly ban gay men.
you have silly ideas about screening, a newly infected HIV case won't register on test for weeks.
20% of heterosexuals don't have HIV, 20% of gay men do
be happy lesbians can donate
disagreed. the fear of disease is quite justified, the percentage of gay men with AIDS is very high, CDC says 20%.
think of the Jewish and Muslim vampires, you insensitive clod!

very likely,
most of the time life on earth was single cell organisms. that's the likely inhabitants of most worlds that can support life
not a lie that the Nazis did this in other countries, registration first then confiscation.
Jews were not allowed to own *any* dangerous weapons including guns, lookie what happened to them
more to the point, there are currently certificates for 1.8 million "firearms and shotguns" in the UK, with the bulk being 1.3 million shotguns

people do own guns, particularly long guns, in the UK. 22 rimfire is in fact the one legally permitted semiauto caliber

no need to jump from high place, just jump along with a very heavy weight that gets removed to the side when the trampoline is at maximum displacement
