Earlier quoted context omitted.
Their ultimate agent product strategy feels like reducing cost of sales... by automating salespeople. I have doubts that will ever happen, but who knows? Sales folks are highly-compensated, so even making a few of them redundant (or making existing salespeople more efficient) would be a big win for companies (Salesforce's customers).
Salespeople are typically compensated based on commissions. At least the well compensated ones are. Automation can make things easier and streamline the sales process, but because the sales rep is paid a percentage of the GP of a sale, automation doesn't really their take.
We can get into the nuances of advantageous tax treatment or not, but sales commissions come from somewhere and are essentially transaction costs.
