They must have run into very strange and unexpected artefacts to have to rely on machine learning to correct this...
Or someone developed a new deconvolution algorithm some time between feature freeze on the instrument package (2012, thereabouts?) and today, and it turned out to be particularly more useful with the AMI focussing-aid.
But it's on-the-ground post-processing, so it can be retrospectively applied by any researcher on their "proprietary" period data, and by anyone else to non-proprietary data in the STSI archive.
Do you have any idea how competitive the process of getting observation time on JWST is? Something approaching 10% of time requests get granted. The other 90% don't get granted.
Your sketched procedure fails at
1. Take lots of photos of the same shot
And again at
2. Repeat step 1 for a lot of overlapping images
Curiosity (and Perseverance) are in a different situation - while the arm/ drill/ XRF tools are nose-up on a rock doing one set of analyses, the cameras can be more-or-less independently pursuing the sort of photographic oversampling you're talking about. The data from, say, an hour of XRF scanning is going to use a lot less bandwidth to Earth than an hour of imaging data.
Building design tends to go for a 2:1 safety margin between expected loads and design strengths. Bridges tend to be a lot more conservative 6:1 or 8:1 between design strength : expected load.
There are good arguments you can have whether a design (and construction process) should have an 8:1 safety margin, or a 6: 1 margin, into which you can easily get a 60% materials cost. If you can justify the lower safety factor and lower cost.
As the Forth road bridge example I just mentioned upthread illustrates, changes in vehicle design can seriously impact the expectations for a structure. The introduction through the 1980s of increased lorry weights from 28 tonnes when the bridge was designed and built to a maximum of 44 tonnes when a replacement bridge was commissioned lead to increased rates of wire breakages in the suspension cables and
So, order of a hundred years?
Note : you asked about "bones", not fossils. The process of turning a bone (any tissue, really, but most often a bone or a tooth, for a vertebrate) into a fossil is a subject of it's own, stretching in effects from forensic science, through archæology and into regular palæontology Look up "taphonomy".
A 100 year lifetime isn't at all unreasonable for a structure. No structure is eternal (though the Pyramids are making a decent attempt - they'll probably not make it beyond their half-million).
I was driving over the new Forth road bridge recently, eyeballing the 140-odd year old riveted cast iron of the Rail Bridge, and the old road suspension bridge (which made it past it's 50 year design life but didn't make it's century because of increases in vehicle loads and counts leading to accelerating wear rates). I wonder how they're going to bring the old road bridge down? Dismantling, or dynamite? There are enough ships using that channel that dynamite has a *lot* of difficulties.
The sheer irony of Microsoft - Microsoft, of all people/ corporations - protesting about the bad effects of ransomware and extortionate demands.
I don't know if you could make up something as funny intentionally, but it's certainly beyond me.
How many people drive a pickup with a huge cargo bed that only gets used a couple times a year?
In this country? I can't remember seeing one that didn't have a company's logos down the side. Oh - tell a lie ; one of my neighbours uses one. It's a day-to-day load shifter for his building work business, but he doesn't waste money on vinyls for it. He has a normal car too, and they alternate on the street outside his apartment.
That was well-known decades ago.
These are policy solutions. (Because "You can't shop your way out of a monopoly," Doctorow warns.) And otherwise, as Doctorow says earlier, "Once a company is too big to fail, it becomes too big to jail, and then too big to care."
In the mean time, Doctorow also makes up a new word — "the enshitternet" — calling it "a source of pain, precarity and immiseration for the people we love.
"The indignities of harassment, scams, disinformation, surveillance, wage theft, extraction and rent-seeking have always been with us, but they were a minor sideshow on the old, good internet and they are the everything and all of the enshitternet."
