Not really. Google hired LLVM and Swift dude for ML stuff. LLVM and Swift dude decided that although Google already had some LLVM, it still needed more Swift, and for ML specifically. This must have struck probably the majority of people in ML who are not him as slightly bizarre (notable exception: Jeremy Howard). Now he's left. I would be truly amazed if Swift for ML goes anywhere.

It's pretty clear that since Chris Lattner left Google the Swift Tensorflow version isn't really going anywhere.

They are still paying a bunch of expensive devs to work on it, so maybe not.

It looks more like between 3 and 5 devs, who probably came on at the same time as Lattner. It's roughly the same as the Java interface for TF has, and much smaller than the microcontroller TFLite team.

That's lost in the TensorFlow team budget.

More like 9 to 10 devs
