Xtensa is not as popular as ARM. Why doesn't ESP8266 use the more popular ARM which would be a safer choice given its long track record?

We don't know all the internal politic decisions done by Espressif, but it is possible that licensing cost was an issue.
They probably paid less for Xtensa design.
BTW, ESP32 is still using Xtensa.

I did think it quite odd, but, after playing around with it in ASM for quite some time, I don't really want to complain. They are different - yes. Constants are a little annoying, yes. But, given the option of a cost/power comparable ARM (would probably be less MHz), I think I'd still want the xtensa.

Big companies like Qualcomm are also using xtensa in some products. Good to have options.
