Sorry, to explain: Bixby is Samsung's attempt at jumping on the "intelligent assistant" bandwagon. It's technically pretty good, but it has been pushed down Samsung user's throats by being non-uninstallable, having a dedicated button on the phone to enable it (that is really hard to disable), and trampling over Google assistant in random ways (like causing occasional issues with Android Auto etc).

It's a lost cause that Samsung refuse to admit should be dead. It's pretty much the canonical example of Samsung making good hardware, but having a terrible plan when it comes to software.

Honestly, I figured everyone on HN would have at least heard of Bixby, as it's been a garbage fire for the last few years, and it touches on ML / mobile / questionable business decisions and terrible UX. This seems like a Venn diagram that includes ~90% of HN users.

Bixby is just Samsungs personal assistant program. Similar to Siri or Alexa.

I think it's reasonable to expect the HN crowd to know what Bixby is and why it's relevant. I agree that the comment doesn't add much to the discussion, though.
