@ThePadawan Got it now! WhatsApp did a great job in tricking users with their interface. No other pun intended, but it fits perfectly in the context: "What's the App?"
I remember I missed a few calls from my mom recently, and she asked me if I noticed her missed calls. I didn't have any missed calls as she was calling me through WhatsApp, but in such a way that she thought is the "regular" way of calling. I explained, now she knows. Not sure where this is going...
I just finished this book and I think it's the most down-to-earth approach towards selling. It even suggests an alternative title for "salespeople" that wants to help others make progress, which would be "concierge."
Looking forward to digging deeper into the Jobs-To-Be-Done theory with Clayton Christensen's book on "Competing Against Luck"
