Yes it seems so! But it's different to the browser wars because the browsers used to used sensible amounts of RAM, and these "modern" chat systems seem to like ballooning quantities of RAM for displaying text and pictures, eg. Slack on my Mac is using 365MB of RAM via its 5 processes.
If only the wars was about efficient applications then we would all win.
I recall using MSN Messenger on a machine with 64 MB of RAM I think and it did approximately the same - instant messaging.
well chrome has won the browser wars in the long run and chrome is notorious for its memory hunger. So maybe RAM hogging is the key to success.
Interestingly Teams uses >1.2GB of RAM via its 6 processes on my mac, same as Outlook.
