pis have gotten less exciting over the years.

for those who are purely using the compute side of the pi is not as interesting anymore due to the flood of both 3rd party options, as well as used dirt cheap micro pcs (e.g Optiplex 9020 micros, 7040 micros, thinkcentre 710q)

and for those who program , they have to split based on usecase. for pure robotics and less compute, there isnt much of a reason to use a pi over an arduino. for IoT, using ESP32 are more useful for device to device communication, so pis sat in this weird spot where you needed it for basic compute (e.g. some object detection) or you needed the community behind pi. but since pis are being bought out by corpo, doong hobby work on a pi is too expensive nowadays. to me, pis died after their pricing tiers for memory not really being great (2019)
