This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Notes -
Starlink brought in $4B in 2023, up from $1.4B in 2022, latest estimate $6.6B for 2024. Development via investment dollars is much faster than via cash flow alone would be, but it's not a necessity.
The bright side of having a problem so bad you want to graph it on a semilog plot is, it gives you room for multiple revolutions.
And your prediction came true - the first revolution did already absolutely happen, even with launch vehicles that are only partly reusable! I used to summarize this as "first place is SpaceX, second is the entire country of China, third is the rest of the world put together", but looking at the latest numbers, that still understates things. Q1 2024 saw launch upmass that was around 86% SpaceX, 6% China, 7% the rest of the world put together.
The thrilling news from Blue Origin so far this year was that they launched two BE-4 engines (original ETA: 2019) on the first Vulcan Centaur test. Again, "understates things" understates things here. The thrilling upcoming news is that they might launch New Glenn later this year (be sure to go to the New Glenn wiki page for that, though; the BE-4 page still says "The first flight and orbital test is planned for no earlier than late 2022,[27] although the company had earlier expected the BE-4 might be tested on a rocket flight as early as 2020.", because apparently editors there have the appropriate level of excitement here), and if they evolve it twice as fast as SpaceX did once they got their first partly-reusable launcher to orbit, they'll have a Falcon-9-killer by 2030, tops. Hopefully I'm being too pessimistic here, but Bezos himself shares my pessimism: see "Amazon buys SpaceX rocket launches for Kuiper satellite internet project" from last year.
Very nice, now show me their costs so we can calculate the profits...
The overwhelming majority of their launches is Starlink itself, a project of unknown profitability / sustainability.
To Mars... on first attempt...
So... what's your estimate on Starship being functional under those assumptions?
