There is value in Boston Dynamics, but will take long time till they create mass market products. They will have specialized products for special areas, but those will be small series, where running production is expensive and a high margin isn't possible. (If a human is cheaper than the machine there is little reason to buy the machine) Value for WhatsApp comes from the fact that it threatened Facebook's business model. If people use other than their products they have an issue. There is also an option for revenue growth (not only ads, but also payment processing etc.) Question is how that will play out with current outcry regarding Terms of service changes ... whether that will have an impact. But for Facebook certainly valuable decision. Slack and Salesforce is more interesting. There is of course the market - others tried to acquire Slack as well, driving the price up. How much it will bring Salesforce (also in Cross-Sales "hey, want some CRM which integrates well with Slack? We have something!") is to be seen ...
