I lost count of the ways this article misrepresented and misinterpreted the underlying research.

No, it does not “replace the metal in future computers” the thing it’s promising to replace is specific kinds of non-volatile memory which is typically made from specially doped and patterned silicon with metal interconnects. Replace the silicon part does nothing about the metal part and it still requires the metal interconnects to do anything interesting.

No, memristors alone are not a good stand alone memory storage devices.

No, a <6KHz with <90% accuracy is not a “grow at home replacement” for modern computing memory systems operating at >2,000,000KHz signal speeds with >99.999999999999% accuracy rates (measured as ~10^-12 bit error rate).

Cool research, potentially interesting applications to neuromorphic computing but FUCK this blatant misinformation slop.

Yes. However the frequency it blocks is ~2.45GHz which is the same frequency as WiFi, Bluetooth, etc. and used to be the only other antenna other than the cellular antenna, where the frequency ranges from 600MHz-2.5GHz.

This used to be good practice because you would first remove the sim card disabling the LTE communication, unless the hardware was compromised, and then place it in the microwave to disable all other signals.

With the introduction and proliferation of eSIM on both devices and carrier sides, removing the SIM card no longer provides much protection and the additional of many other communication methods, most notably 5GHz 802.11x, the microwave trick doesn’t really do anything either.

But it used to work.
