The vast, vast majority of chips produced are "old generation" chips used for relatively mundane purposes. The high-tech stuff you see in the news is a minority (though it's pricey enough that it doesn't look that way in company earnings reports).
Think power supplies, middle-of-the-road CPUs, ASICs for common I/O like USB and ethernet, timing devices, and wireless communication modules.
And that's mostly the "bullshit IoT" category. It's not like the demand for phones and laptops exploded in the last years, it's IoT, AI and other useless crap - regardless of the process node.
Even a non-IoT electronic device still runs on many different chips.
