I would have thought that the real competition was the ESP32. It stays in the microcontroller space (no OS to manage, should stay lower power, etc.), dirt cheap, ships with wifi+bluetooth.

I'm doing a hardware selection and after much consideration, I'm picking a 3$ esp8266.
I don't see any purpose of Arduino outside education for kids. Makers should use cheaper products/knockoffs at worse.

The ESP8266 doesn't have hardware PWM, and only a single ADC channel, both which can make it unfit for a lot of tasks.
That said, it does come with a lot of SRAM and the wifi/bt connectivity is obviously great.
The only very slightly more expensive ESP32 boards have 18 ADC channels, 16 PWM channels, and 2 DAC channels.

Yeah the ESP32 is pretty darn awesome.

There are actually hacky ways to work around that using DMA but yeah. Software PWM sucks.
I recommend trying the ESP32 as well (more pins for ADC and a few other features).
Either way, the ESP's are an incredible value (I use both).
Same. I have a bin full of esp8266's that have become my go-to for little projects. Going to play with esp32's when I run through them
Fortunately ESP32 does have an OS, so you can use all kinds of niceties (multitasking, bootloader, etc.).
Which OS are you referring to? FreeRTOS or something else?
