Right. I agree that Slack is nowhere close to overtaking email in absolute terms. But I suspect it is growing faster than email. Your figures project email users growing by 11.5% over the next four years. Slack is growing by that rate every quarter (at least).

Not hard to grow fast when you're starting small. If I launched a new chat service later tonight, it'd be the fastest-growing communication technology in the world tomorrow, since it'd be going from one to two or three or possibly even four users. Slack would kill for a 300% daily growth rate!
Sure. Think it'll maintain that pace for more than a couple years? Especially given the strange interest in chat bots that people seem to also have.
I am honestly so perplexed by the bot mania.
Don't get me wrong, they have their uses, but how is this suddenly perceived as a multi-billion dollar market?
