8-bit parts are still around, but the cost savings often isn't worth it for smaller volume production compared to 32-bit MCUs. Easier development saves a lot of money. 32-bit parts are dirt cheap, and the varieties with built-in WiFi or Bluetooth or such are usually cheaper than separate MCU + radio + development to integrate the two. 8-bit flip-chip parts are even cheaper, but the bill of materials (BoM) savings aren't big enough to pay for the added engineering effort to use them for anything but the simplest tasks or the biggest volume products.
