How do you reach the conclusion that you did? From TFS:

On its face, that contradicts the idea that Whoever has the "biggest computer" can lock up all of human progress and collect rents for it into the future -- a natural person still needs to conceive of the invention, rather than patenting the output of tool that happens to be the "biggest computer".

The problem here is geekmux, not Excel. I've never heard of somebody saying a spreadsheet does, or should, "track[] to 42 decimal places". I don't even know what you meant by "rounding accuracy that makes GPS timing look like a 19th Century pocket watch" -- I can tell you what kinds of errors exist for different GNSS satellite and receiver clocks, but rounding errors are dwarfed by others.

If you have some technical complaint, be specific about it rather than trying to be cute, because you run a risk of making yourself look stupid rather than clever. There are some well-known problems with Excel's default behavior, like how it aggressively treats text as dates -- but a lot of spreadsheet errors and loss of precision are purely user errors.

When all spaces are full, you can't park there anyway, independent of the question if there are 9 or 10 occupied spaces.

Driving from Dublin to Donegal means that you take a short cut through Northern Ireland. Crossing the border is an everyday occurrence. And that border is one of the main reasons why a) Northern Ireland voted against Brexit and b) the Brexit negotiations were so complicated, as it is easier to levy tariffs on the ferries between Northern Ireland and Great Britain than between Northern Ireland and the Republic of Ireland.

But that's where most border crossings happen from the UK. It's not the edge case. It's most of the cases. For all other border crossings, you would have to book a ferry.

There is no passport control at the border of Northern Ireland and Republic of Ireland. (And between most E.U. countries).

There is also the Mountain Pass Rare Earth Mine in California.

It has been opened and closed several times as the Feds and state of California tussle over it.

California greenies want it closed. The Feds want it to operate, even at a loss, for supply chain security.

It is currently operating with DoD subsidies, but production needs to be ramped up.

It always boils down to the question: Does it matter?

Does it matter if you have 9 or 10 dollars, if all you want is to buy an ice cone for $3.50?

Does it matter if there are 9 or 10 parking lots if you know 5 of them are occupied, and you want to park your car?

Sometimes, 9 or 10 is a question of life and death. Are there 9 or 10 people in the burning building, and have we account for all of them rescued from the fire? Sometimes it is totally irrelevant.

Same with Dark Matter. If we want to account for effects on cosmic scales, it is really important. For gravitational effects in our Solar system, not so much.

We could also call it "apparent gravitational effects, which don't fit our models right now, but would fit perfectly well if we assume about five times more mass than we can actually account for."

No, it's Nibbler poop, as we all know.

People have a very important source of knowledge which is totally missing from AI: experience.

A person knows what "hot" means, because it has touched a hot surface during its lifetime at least once and felt the pain. A person knows how a speed bump affects the car ride, and how lemon tastes. A person knows which shape fits into which hole, because as a child, it has played the game.

Persons learn all the time by formulating hypotheses about the world and then experience how it works out.

AI totally misses this feedback. Or as my father uses to say: AI talks about color like a blind person.

The illusion of intelligence evaporates if you use these systems for more than a few minutes.

Using AI effectively requires, ironically, advanced thinking skills and abilities. It's not going to make stupid people as smart as smart people, it's going to make smart people smarter and stupid people stupider. If you can't outthink the AI, there's no place for you.

DuckDuckGo's LLM generates this, for example

... (emphases added) and if you click "more" it may change to say that RHD vehicles drive of the *left* side of the road (LHT, which is true).

The Spain outage would have happened with Nuclear exactly the same way. It was not a problem of not enough power. It was a problem of too much power, which was not absorbed by the consumers, and caused a build-up of over-voltage, which could not be dumped anywhere. When the grid automatically switched off power sources to damp the swing, it over-corrected, leading to a power loss of more than 2 GW, which then caused the shut-down of large electricity consumers. With a fat nuclear reactor, you would not have changed anything. Still, the grid regulation would have overreacted, with the same consequences.

Where I live, a railroad crossing limits the top speed of the rail to 80 mph - definitely not high speed rail.

High speed rail is always grade separated. (How many non-grade separated roads you know which allow for a high speed above 80 mph anyway?)
