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.

No, the problem is greedy corporations.

There is an active need for many developers, think of every time you’ve used terrible software, every time a program crashed or you found yourself manually doing something and thought “there should be a tool for this”, every bad search and broken social media site.

Hell, we’re supposed to be in the middle of an “AI boom” and someone has to actually implement all those pie in the sky “automate away everyone’s jobs”. While AI can, debatably, write the code for that, it still takes a person to design, architect, implement, test and validate those systems.

No. The entire technical foundation on which “computer science” is built is crumbling due to lack of maintenance and funding and desperately needs people to fix it, however corporations are doing their what they do best; devaluing, destroying, and parasitizing their surroundings.
