An ESP32-P4 is about the same ram, better IO options, but half the CPU of the original Pi for about $20 right now. So the tech has been progressing a little bit.
The Pi Pico is a 32-bit processor for far less than $20.
A microcontroller is in a completely different category from the Pi 5
Theres a ton of ebook readers that are using the esp32 as a baseline. and meshtastic. Its a fantastic set of chips and setup.
It's also been 14 years. "About the same ram...but half the CPU" for over half the price (original comment was wrong, it was $35, not $15) is not a flex. It's a stunning failure.
The economic aspect of Moore's law has been broken. Luckily we still have capabilities for a few more years of innovation in the performance scaling. For now.
The original Pi had 512MB not KB. It ran Linux and had an SD card "disk". The ESP32 series aren't in the same class.
