A Tcl article and an Erlang article - good morning!

I miss working with Erlang especially, but it's also certainly kind of a niche thing. Other languages are faster and have more effort being put into them.

and 32-bit arm (nothing wrong with it; just like tcl and erlang, it's alive and well)

For a certain definitions of faster

Don't Erlang and Elixir have a lot of effort being put into them?

I don't have any experience with ARM, but from what I've seen people write, isn't 32-bit ARM discontinued after v7?

There's still a huge embedded market!

Plenty of microcontrollers have a single-digit number of Cortex-M cores and memory/flash counted in the megabytes. It'll be decades until that market reaches the multi-gigabyte point, so why bother wasting a whole bunch of memory on 64-bit pointers?

I'm not quite sure why you'd want to run Erlang on it, but the hardware exists.

No, it's a supported ISA on most v8-a and I believe all v8-m implementations.

It's the only ISA on Cortex-A32, but not sure if any mainstream chips were ever produced with that core.

(Depending on course if you want to get specific about Arm/Thumb/Thumb2, I lumped them all together above).

That does not mean ARM32 implementations and uses are stopping any time soon. Afaik arm hasn’t even obsoleted armv6, although Linux distributions are starting to drop it.

Doesn't mean that machines won't be built with other chips for a considerable time.

That said, if you're putting something like Erlang on a chip, aren't one likely to want the extra memory (and performance) of a slightly newer SoC.

Cortex-M chips will still be made for decades.
