Submission + - The world's tallest chip defies the limits of computing: goodbye to Moore's Law? (elpais.com) 1

dbialac writes: Building chips up instead of smaller may be a solution to the problems encountered with modern semiconductors.

Xiaohang Li, a researcher at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia, and his team have designed a chip with 41 vertical layers of semiconductors and insulating materials, approximately ten times higher than any previously manufactured chip. The work, recently published in the journal Nature Electronics, not only represents a technical milestone but also opens the door to a new generation of flexible, efficient, and sustainable electronic devices. “Having six or more layers of transistors stacked vertically allows us to increase circuit density without making the devices smaller laterally,” Li explains. “With six layers, we can integrate 600% more logic functions in the same area than with a single layer, achieving higher performance and lower power consumption.”

The "de minimus exemption" isn't a loophole or cheating, it's a choice by virtually every collecting tariffs to only collect tariffs from large cargo shippers, not one-off purchases, because it's a waste of time and money to do the import duty paperwork for every single little item shipped. The whole system globally, for all countries, does the same thing because they don't want to charge a typically $50 or so processing fees (to cover the manual labor and processing fees for doing the paperwork with the various governments) in order to collect a few dollars in tariffs, they want to focus that work on tariffs for bulk shipping containers, etc., not wasting their time on tens of millions of individual items. In response to the US cutting the de minimus exemption dozens of countries have stopped all shipments to the US as they're not prepared to process an increase of several orders of magnitude in the volume of bureaucratic paperwork, so other than letters and gifts under $100, which aren't tariffed, they're cutting the US off.

Apple has a long history of replacing proprietary with open standards, working with the open standards to make them good enough to replace the proprietary tech. Apple likes to have the option of innovating, e.g. ADB was better than the serial ports for keyboards and mice that PCs had, then they worked with Intel to create USB that replaced ADB. Similiarly, Apple had early cheap LANs when ethernet was very expensive and fragile, then when ethernet got cheap and easy Apple moved to ethernet. And they helped create USB-c, and adopted it aggressively, giving it the advantages of Lightning, replacing older tech. The only lightning ports they still had when the EU mandated USB-c were on low end (low power, slow data) phones, keyboards, and mice, where Lightning worked well. Desktops, laptops and iPads were already USB-c. Moving the low-end devices to USB-c wasn't bad, and I don't think Apple fought against that, they just don't like mandated tech, because it prevents them from future innovations. For example, if the EU had mandated USB-a, then that would have blocked USB-c, so the both like open standards and they like the ability to innovate, they balance the two.

It would let you see where Apple is heading, giving you hardware and software to develop for, letting you start developing and prototyping to be ahead of the game for the future market, when Apple works down the price into a higher volume AR product. As Tom Cook and others explained in interviews and presentations.

Apple has a much higher success rate than most product companies. They're famous for killing off numerous internal products that could have been "fine" because that's not good enough, they want "amazing". They don't always succeed, of course, but many companies would have shipped things Apple refused to.

Yes, Apple's products are for people willing to pay more for better, not for people buying the cheapest possible solution. That's not bad positioning, they dominate the high end phone market, for example, last time I saw the numbers they made 85% of all the profit on selling smartphones globally, Android phone sales are more units, but mainly just breaking even on low-end phones. (Yes, there are some high end android phones...)
