Microsoft's Copilot+ PC push is officially everywhere, and if you bought a laptop in the last eighteen months, there's a decent chance it's quietly pretending to be smarter than it is.
The pitch is simple: a dedicated neural processing unit, or NPU, handles AI chores on-device so your battery doesn't evaporate and your data stays local.
Recall, the feature that snapshots everything you do and lets you search it later, was the headline act.
Then security researchers found it storing screenshots in a way that made everyone's eyebrows climb into their hairline.
Microsoft delayed it, bolted on encryption, and relaunched it like nothing happened.
Meanwhile, the actual "AI features" shipping on these machines are a grab bag of things you already had.
Live Captions translate audio in real time, which is genuinely neat.
Cocreator draws pictures from your scribbles and looks like a fever dream rendered in watercolor.
The rest is mostly a chatbot key that opens a chatbot, which you could already do by, you know, opening a chatbot.
Here's the part the spec sheets don't tell you.
Those NPUs are rated in TOPS, and the marketing wants you to believe more TOPS equals more better.
In practice, most apps still run in the cloud because local models are too small to be useful and too big to be fast.
You're paying a premium for silicon that mostly sits there, warm and unemployed, like a treadmill in January.
Qualcomm's Snapdragon X chips kicked the whole thing off with great battery life and a nasty surprise for anyone running older software or certain games.
Intel and AMD have since caught up with Lunar Lake and Strix Point, and the compatibility headaches have mostly faded.
Apple, notably, has been doing this quietly on Macs for years without a single keynote slide screaming "AI PC" at you.
If you're shopping for a new laptop anyway, sure, grab one with a decent NPU.
It future-proofs you a little and costs basically nothing extra at this point.
If you're happy with your current machine, there is no killer app waiting to justify an upgrade.
The honest truth is that "AI PC" is a category invented by marketing departments who needed a reason for you to buy a computer in a year when computers got boring and good.
My take: buy the laptop you actually need, ignore the sticker, and let the software catch up on its own schedule.
Final Thoughts
The NPU will still be there in two years, probably still waiting for something to do.
