This is probably the most unnecessary thing I have seen as a Copilot use case. Was the SUM function really that hard? =SUM(A3:A1) and most of the time you don't even have to type it. just...why?

I think it saw A as the column header, assumed this was Hex, added everything up, and then converted back to Decimal and got 15, because off-by-one errors are unavoidable.

[–] ech@lemmy.ca 50 points 2 weeks ago* (last edited 2 weeks ago) (2 children)

There was no thinking, "assumptions", addition, or conversions. It saw numbers and generated another number that hit it's "this should go next" filter first.

[–] o_oli@lemmy.world 22 points 2 weeks ago (1 children)

Yup...the comment above yours is giving copilot way too much credit lol. That shit needs to stay a 1000 miles away from Excel.

Excel is already a global nightmare, with so many jank should be databases run on it, with AI on top...oh boy.

That's very true, my comment was meant to be tongue in cheek but that may not have come across fully

[–] ech@lemmy.ca 9 points 2 weeks ago

All good. It's just something I see a lot of people say without sarcasm or irony a lot, and I think it's a dangerous assumption to have about these algorithms. The personification of them has been the biggest boon to the over-hyped adoption and investment they received these past years, so I generally make a point to clarify when I see it, if only to better inform those who might not realize.

Is copilot written in JavaScript? Concatenation of ints......

Copilot is for entertainment purposes only.

[–] massive_bereavement@fedia.io 27 points 2 weeks ago

well this was entertaining. Mission accomplished.

[–] wonderingwanderer@sopuli.xyz 3 points 2 weeks ago

Are you not entertained?

I worked in finance for 14 years. If you think that AI is going to markedly decrease the accuracy of the Excel spreadsheets underpinning our financial system, then you've never seen those spreadsheets.

I once saw a formula that ended in "+15". Because that's what it took to get it to balance. It was like that for years.

And honestly I worked at one of the better banks, one of the ones that didn't actually need to take the TARP loans.

I found that to be a turning point in my life after working a few years at a real job at a respectable place and realized holy shit even the big places are full of people that have no idea what they are doing and lots of stuff is just winging it. Its really scary when you realize it.

[–] moakley@lemmy.world 17 points 2 weeks ago* (last edited 2 weeks ago)

I found it reassuring. It turns out winging it mostly works! The systems still run in spite of flaws.

[–] ptu@sopuli.xyz 7 points 2 weeks ago

There is almost always some sort of discrepancies in the figures. That’s why the auditors never say that the numbers are ”correct”, instead they ”present fairly, in all material respects, the financial position”.

CoPilot already is a global financial crisis, in that it represents trillions of dollars of misallocated capital in the US AI craze.

[–] wonderingwanderer@sopuli.xyz 29 points 2 weeks ago (2 children)

Why the hell do they need to replace excel formulas with copilot?

They already do what they're supposed to do: deterministic math operations. There's no need to "improve" on that with non-deterministic LLMs...

[–] Rooster326@programming.dev 23 points 2 weeks ago* (last edited 2 weeks ago) (2 children)

Because Microsoft spent $35 Billion* dollars on AI and needs to see a return on the investment or they're fucked.

  • And rising
[–] wonderingwanderer@sopuli.xyz 4 points 2 weeks ago (3 children)

What, do they think this is gonna convince more people to sign up for their license? Or do they expect people to pay more for it now?

Either way, it's likely to backfire as people abandon ship for FOSS alternatives...

[–] technocrit@lemmy.dbzer0.com 5 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

Either way, it’s likely to backfire as people abandon ship for FOSS alternatives…

Legal entities will continue to use shitty proprietary software because of the liability. It's more important to have a legal backstop than actual security... It's security theater. It's a big part of why nothing is actually secure in USA. Casino griftonomics.

(I've been thinking about this in terms of the MIC too. Total failure against Iran. The iron dome lmao. They're pouring endless money into these grifters who almost never have to demonstrate quality/effectiveness.)

IIRC Calc, which is one of the alternatives that is closest to parity still needs a significant investment of time and resources to be on par with pre-Copilot Excel when it comes to performance and functionality.

It gives them excuse to dark pattern people in to a higher subscription tier, also shareholder want to see them selling AI products, and they want to keep their share price high because the decision makers are all payed based on market cap.

Shareholders want to see them selling AI products because they also have stock in Nvidia. More AI products, more demand for data centers, more demand for Nvidia chips. Everyone else pays more for less so people who live on investments can fund a lavish lifestyle.

Me: opens a new Excel document, enters the number 7

AI: here's a summary of the contents of this cell: the number 7. It holds significance in several religion, is the number of days in one week, is a real number, and is a prime number.

Suspicious cropping on the left hand side. If you open up excel, that is not where single digit numbers are oriented in the column underneath the triangle. They do have the orientation of two digit numbers who's 10's place has been cropped out though.

What's happening here isn't AI giving a wrong answer, it's someone who has more numbers entered above and has cropped the image to make it look like AI hallucinated. The rows shown aren't 1-4, but 11-14.

There are lots of reasons to hate AI, but don't fall for fake rage-bait. Especially when it's so low effort.

[–] drolex@sopuli.xyz 4 points 2 weeks ago

And do you think I will react reasonably with the rational and factual information you gave me? Because, yes, I will, so thanks for your analysis

[–] aufbau161@lemmy.blahaj.zone 15 points 2 weeks ago (2 children)

iirc this one has been debunked. i think the crop was deliberately done so closely so that you couldn't tell that it wad actually row 11, 12 and 13 and not 1, 2 and 3. so the math behind it might add up correctly. (full disclaimer: i hate copilot with a passion, despise LLMs like the next person [if the next person hates LLMs a lot, otherwise i skip that person] and hope for the bubble to pop rather sooner than later and fuck me i wished that screenshot was real but alas it didn't seem so)

[–] Zexks@lemmy.world 4 points 2 weeks ago (1 children)

Whats rrally sad is nearly every other comment is just acceptung it as straight fact

[–] Rooster326@programming.dev 3 points 2 weeks ago

Yes, won't someone think of the the poor LLMs.

[–] BlackPenguins@lemmy.world 2 points 2 weeks ago* (last edited 2 weeks ago)

Damn you're right. I can totally see the crop and the fact there's probably 10 other numbers.

[–] pruwybn@discuss.tchncs.de 15 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

I have to use Excel for work. When I right click to paste data, now there's a bullshit Copilot command right where Paste (edit: actually "insert copied cells") used to be. I swear they chose that spot just because it's used a lot and they knew they could cram it in more people's faces that way.

[–] prenatal_confusion@feddit.org 6 points 2 weeks ago* (last edited 2 weeks ago) (4 children)

Ctrl + v

Or is that copilot too now!?! Oh dear, don't give them ideas.

[–] pruwybn@discuss.tchncs.de 2 points 2 weeks ago

I guess it's specifically "insert copied cells" that I was thinking of.

Oh please can AI just fuck off for once and keep going? Surely this shit has to pop soon. Otherwise I'll have to learn all about data center sabotage, and that seems like work.

[–] OwOarchist@pawb.social 4 points 2 weeks ago* (last edited 2 weeks ago) (3 children)

Otherwise I’ll have to learn all about data center sabotage, and that seems like work.

Well, data centers usually have fairly tight security, so your first challenge is just getting access to it. There are five main approaches you could try:

  1. Infiltrate: Apply for datacenter jobs and try to get employee-level access to the facility. This is likely your best shot, but depending on your background, it may be difficult or impossible to achieve. It will also be extremely difficult to maintain your anonymity while doing this, so you're very likely to be caught.

  2. Assault: Datacenter security is designed around keeping out a sneaky, lone, unarmed intruder. A rapid application of brute force and violence could probably break through security and gain access. But alarms will definitely be tripped, so you'll likely only have a few minutes before police backup arrives.

  3. Long-Range Assault: Using drones, rockets, long-range rifles, artillery, trebuchets, whatever heavy weaponry you can get your hands on, attempt to damage the facility from long range, from well outside of its security perimeter. Unless you can get/build some very impressive weaponry, damage is likely to be limited and localized, but you could conceivably get away with it without getting caught if you 'shoot and scoot' and cover your traces well.

  4. Stealth: Try to find holes in its physical security and sneak through without being noticed (including by impersonating staff without actually getting hired). Since this is exactly what their security is designed to prevent, it will likely be the most challenging option, but it's possible there are still vulnerabilities in their security that could be exploited. If you do manage to make it through, you could potentially cause a lot of damage and still manage to get away without being caught, so it's a high risk/high reward strategy.

  5. Hacking: Instead of trying to get physical access to the datacenter, you could try to hack into it and gain electronic access. However, this is likely to still be fairly difficult unless you're extremely skilled in hacking, and the damage you can do is limited because you won't have much opportunity to cause hardware damage. This will (mostly) be limited to causing temporary outages before they restore from backup. (Though if you could manage to set off the fire suppression systems...)

How exactly you actually go about damaging the datacenter's systems will depend heavily on which method you're using to gain access. Different methods open different possibilities.

The x.com watermark really puts this over the top in terms of representing how stupid everything is right now

Well then maybe we shouldn't have banked the entire global financial system on proprietary software from one of the shadiest corpos on earth, huh?

[–] SupraMario@lemmy.world 3 points 2 weeks ago (3 children)

You mean COBOL? Cause pretty much every bank out there still has shit built with it.

I believe the explanation for this is the first cell is formatted as text. And summing text concatenates rather than adds. Then the new value is saved as a number, adding the 3, to get 15.

This is an error that can already happen in Excel and one any experienced Excel user has to look out for when moving between alphanumeric and numeric cell types.

[–] _stranger_@lemmy.world 5 points 2 weeks ago (3 children)

so you're saying people who don't know what they're doing shouldn't use tools they don't understand to do things that could cause huge problems if they go wrong? How dare you admonish the Dunning-Kruger field generator!

That’s exactly correct, assuming your sequence is numbers k such that phi(k) divides k+1, where phi is Euler's totient function
