I doubt it. I think this is a replacement for the existing on-prem Outlook, as well as replacing Quip and Workdocs which have been languishing for years. But I really doubt this replaces Slack/Chime for chat/video respectively.
Teams is a horrible software, but every single aws person I have talked to would love to use it instead of Chime.
Not to mention that most of their most important (enterprise) customers are using it.
It’s nice to be able to casually chat with a customer if you are in a customer facing role. Which is basically the entirety of the aws sales and solution engineering.
I know some folks that do management in one of the FCs and they had went from Chime to Slack earlier in the year so I can’t wait to see the sudden dump from Chime to Slack to Teams…
I had exactly one customer that used and loved Chime. For their use case, Chime was also cheaper than getting all their user base on O365.
I also did not dislike Chime when I worked at AWS. Turns out that I have never updated my Chime client from version 4. After I left, I got into a call with somebody at AWS and hoooo boy, what piece of crap the new client is.
The funny thing was people complaining about Chime's call quality and praising Slack's. It's exactly the same thing, Slack video call is a Chime SDK implementation.
