That I've been deeply involved in the design and implementation of both hardware and software for 40 years and know nothing about it, and don't know anyone in the industry who does either, is a comment on the $16B evaluation. Companies thrive on the needs and wants of people which is why Coke and Google and Microsoft stock prices are so high and maintain those levels. I don't find want and need for Slack among anyone I know. A small space but the same people have heard of and use Coke, Microsoft and Google.
On the contrary, I literally don't know anyone who doesn't know what Slack is. I'm not sure if it's a generational gap, corporate gap, or what, but I've used it at multiple organizations both in and out of tech.
The alternative interpretation of what you have said is that $16B is actually too low and that Slack is undervalued or at the very least it has a lot of room to grow.
