As all this space tech come to maturity over the next 30 years, and we have ironed out at least some of the tremendous issues -- physical, engineering, and biological -- that we already know faces a Mars shot, it will be ironic that during that same time frame the Earth will start suffering some very significant climate issues and global population issues.
We will not have the social or national capital to do much after about 2050. We will be too busy trying to figure out what to do with >2 billion climate refugees.
Elon Musk is this generation's DeLorean w/o the coke scandal.

HIV was supposed to fix that. Turns out it hated gay men more. Our best hope still relies on advanced ebola. Either way we got to get those very low IQ shit hole regions to stop mass producing low IQ populations that they can't even house, feed, and care for.
Nukes, diseases or shark feeding. I'm all ears to ideas.

I always thought gayness was a evolutionary response. But I am simpleminded, as Judy Garland's char in Judgment at Nuremberg so famously declared, NO I am NOT.
Who knows. I think the world needs to get a lot more toxic before we see real evolutionary damage.
But the tides, they are a-rising. And that's a lot of people, and very nice land. The Florida Keys? Goodbye. And so forth.

I don't see the point of launching the super-huge rockets... why not use falcon heavys to launch whatever you need in 40 pieces, reusing every rocket? Or is the starship/BFR supposed to be reusable also?

Well it's supposed to be able to take 100 passengers around the moon at least (he's already got a Japanese billionaire paid into that so he has to make it) and it's supposed to go to Mars.
The size and weight have to do with the much bigger payload obviously but also with the different fuel it uses. BFR uses methane instead of kerosene, so they'll need a lot more fuel to get as much thrust out of the rocket. But methane can be produced on Mars and kerosene cannot. So the idea is the first few unmanned flights would land a methane production facility on Mars ahead of the manned flight so that the manned flight halves the fuel it needs to boost to Mars.
Also Musk is having a press conference in front of that prototype tonight.
EDIT: Starship presser:

There's a paper out that is kind of a 'what if' kind of question - that Planet 9 is a black hole. I wouldn't care / post about it, but thought this was funny:
'Exact scale (1:1)' illustration of said black hole.
Paper is here - [1909.11090] What if Planet 9 is a Primordial Black Hole?

We highlight that the anomalous orbits of Trans-Neptunian Objects (TNOs) and an excess in microlensing events in the 5-year OGLE dataset can be simultaneously explained by a new population of astrophysical bodies with mass several times that of Earth (M⊕). We take these objects to be primordial black holes (PBHs) and point out the orbits of TNOs would be altered if one of these PBHs was captured by the Solar System, inline with the Planet 9 hypothesis. Capture of a free floating planet is a leading explanation for the origin of Planet 9 and we show that the probability of capturing a PBH instead is comparable. The observational constraints on a PBH in the outer Solar System significantly differ from the case of a new ninth planet. This scenario could be confirmed through annihilation signals from the dark matter microhalo around the PBH.

The microscopic ones do, but something earth sized would last 5.668638e+50 years.

Looks great but the only domes with access to sunlight would probably be for observatories and some hydroponics. The vast majority of the agriculture will be LED-lit vertical farms under several dozen feet of regolith to protect it from the harsh radiation.Sometimes, it's time to promote my favorite artist:
Blackbird Interactive (homeworld: deserts of kharak guys) made Mars base exploration demo with NASA called Project Eagle. It's free on steam.

NASA Just Revealed an Ocean on Enceladus Contains The Building Blocks of Life

To be accurate, the building blocks of life appear about everywhere in the universe, since relatively simple chemical processes generate them.

A Cosmic Pretzel - Twin baby stars grow amongst a twisting network of gas and dust
Astronomers using ALMA have obtained an extremely high-resolution image showing two disks in which young stars are growing, fed by a complex pretzel-shaped network of filaments of gas and dust. Observing this remarkable phenomenon sheds new light on the earliest phases of the lives of stars and...
