Yeah, for US money the serial number is prefixed with a letter to donate the year it’s from and the note also has a series year for the actual design printed on it.

Money has evolved a lot since the 1980s so modern money would be obvious. And banks in the 80s would probably be pretty hot on money fraud as hard case was so central to the economy.

A better option would be to collect money printed prior to the year you wanted to time travel to. It’s unlikely they would be able to detect duplicates of real money already in circulation elsewhere in that time. But it might be hard to fine money that old in large volumes as so much gets taken out of circulation and replaced with new money every year.

A steam engine back to Ancient Rome, just to see what they might have achieved with that kind of idea.

This is such a bizarre story. First as others pointed out 1 in 125 is 0.8% not 0.008%. They presumably forgot the 100 but in percent conversions. It’s presumably 0.8% as if it’s 0.008% then they’re saying 9billion devices were sold on the last quarter. At 0.8% it’s 90million laptop devices. They later say 20% of all laptop sales were AI laptops at 13.3 million which would be 66.5 million laptops overall, not 90milljon. 720,000 would actually 1.1% of all laptops and 5.4% of the AI subcategory.

So whoever wrote the article doesn’t seem to know how to do basic maths? They also don’t make clear how they arrived at their figures with these contradictory figures elsewhere in their own article.

But the main thing is this whole story is some bizarre idea that a new device getting nearly 1% of global sales in its first quarter is doing badly?

To me that’s actually good? But maybe the manufacturer had some crazy expectations? Or maybe the writers think that all products should behave like incumbents?

This reads like shitty journalism - trying to make big claims to get clicks. I have no idea if the product is doing well or not versus expectations, but I don’t trust this articles take on it.

I’m personally skeptical about the “AI” bullshit in these products, but I do think the power efficiency of ARM chips may give these Snapdragon X a chance to take market share from traditional chips.
