Raspberry Pi Pico Bit-Bangs 100 Mbit/S Ethernet

Fun stuff. You kids don't know how lucky you are to have really capable MCU's for just a few bucks. :-)

It is kind of the ultimate "not a TOE[1]" example yet.

[1] TOE or TCP Offload Engine was a dedicated peripheral card that implements both the layer 1 (MAC), layer 2 (Ethernet), and layer 3 (IP) functions as a co-processing element to relieve the 'main' CPU the burden of doing all that.

I can't get my head around it sometimes. I know most end up doing duties that a PIC-chip could do but the fact you can get a WiFi enabled microcontroller few a few bucks blows my mind.

The IO co-processing on the Pico is so powerful, I hope they expand on this.
