alt Hacker NewsOver time the Raspberry Pi use case shifted more and more away from GPIO. They all still have it but probably most of them are used as a Linux computer without ever touching the GPIO now. The people who do use GPIO on a Raspberry Pi are often better off using an ESP32 because they have better control of GPIO, consume far less power, and are actually cheap.
Personally I use ESP32s for GPIO to control things around the house and have one Raspberry Pi acting as a hub.

their RP1 IO chip is such a disappointment for high performance GPIO use cases as well, literally can’t trust any IO decision they make after having hacked on that chip
I've been doing home electronics projects since around 2013, I used to use Raspberry Pi's for everything from lighting control to robots, camera projects and lots in between (I even had a mechanical keyboard with a Pi inside) and a massive collection of hats and addons. These days, I can do 99% of what I need with tiny little ESP32 variant boards for a fraction of the cost and significantly less complexity. Hell, you can even get esp32's with really nice touch screens attached for dashboards / animations. I built a whole cyberdeck using an ESP32 and no computer in-sight.
