Yeah, I'd be trying to design at least a live trap system where humans could come by once a week or so to sort and dispose of the pythons. At least until they have a selective trap that only catches the desired pythons.

Figure 1 hour/day maintenance at $30/hour per live rabbit sensor/trap. That's $11k/year. While 1 hour might be excessive for actual labor, figure in the time to actually REACH the traps, which are going to be located in fairly remote spots.
Minimum wage in Florida is $14/hour and going to $15/hour. It's pretty standard to figure that actual employment costs run double once you introduce taxes, benefits, insurance, education, vacation, and everything else.
In this case, the office is likely a 'rough terrain' vehicle.
All expensive.

Oh, and the $4k is probably for the complete setup, which means that even a "cheap" live rabbit setup runs like $2k for the cameras and data uplink.

The setup was pretty much the same for live rabbits - they were kept in cages that the boas couldn't reach. But it was a much larger setup. A bigger cage, water bottle, feeder, it was like six times the size of the pictured toy one.

As noted by others, it's not the acquisition costs that kill, it's the maintenance. Rabbit feed, water, medical, cages, cleaning, etc...

The robot rabbits can be scented from a bottle, the solar panel and a battery keep it emitting heat visible to the snakes (which can see into the infrared), and attract them that way. No more need to carry around feed, water, and replacement rabbits. The robot rabbits can presumably be left in place for longer periods without maintenance.

The authors do not make that claim. They say that more intelligent parents will tend, on average, to have more children who survive to reproduce successfully.

Here's a rather beautiful case in point, from Substack the other day:

"...excessively aggressive mitigation policies could prove more detrimental than beneficial".

Don't you love pompous official jargon? In English,

"...trying to stop CO2 emissions may do more harm than good".

Climbing a molehill may give you a tiny dopamine bump. But climbing a real hill, or even a mountain, will give you feelings you can't get otherwise.

Nietzsche was right when he recommended walking in the mountains. Nowadays that takes willpower, organisation, and persistence.

Still, it's worth it.

I was very sad when I first noticed Amazon reviews of books with reader comments such as, "Too many long words", "Old-fashioned language", etc. Try reading Gibbon's "Decline and Fall of the Roman Empire", or anything by Dr Johnson, or even light reading like Dickens, Thackeray, and Trollope. Some people nowadays would find Mark Twain too heavy and complicated.

"At Our Wits' End: Why We're Becoming Less Intelligent and What It Means for the Future" by Edward Dutton and Michael A. Woodley of Menie.

We are becoming less intelligent. This is the shocking yet fascinating message of At Our Wits' End. The authors take us on a journey through the growing body of evidence that we are significantly less intelligent now than we were a hundred years ago. The research proving this is, at once, profoundly thought-provoking, highly controversial, and it's currently only read by academics. But the authors are passionate that it cannot remain ensconced in the ivory tower any longer. With At Our Wits' End, they present the first ever popular scientific book on this crucially important issue. They prove that intelligence -- which is strongly genetic -- was increasing up until the breakthrough of the Industrial Revolution, because we were subject to the rigors of Darwinian Selection, meaning that lots of surviving children was the preserve of the cleverest. But since then, they show, intelligence has gone into rapid decline, because large families are increasingly the preserve of the least intelligent. The book explores how this change has occurred and, crucially, what its consequences will be for the future. Can we find a way of reversing the decline of our IQ? Or will we witness the collapse of civilization and the rise of a new Dark Age?

Translation of the article: "If you talk gibberish, people may not understand you".

Of course, that may be the speaker's intention.

I see. Just like the Chinese... and the Indians... and the Iranians... and the Arabs... and the Latin Americans...

Everyone, in fact, except the heterogeneous collection of random colonists who stole North American from its indigenous peoples.

How odd.

Racist at all?

During WW2, the USA traded on a fairly large scale with Germany, up till and after Germany declared war on the USA in December 1941 - 2 years and 3 months after fighting began in Europe.

Actually, lawyers, when speaking legally, have their own version of English, often using Latin borrow-words, specifically to counteract any evasive and ambiguous word use.

Don't buy Intel.
