Most of Google's 57,000 headcount is ad sales reps. Before search personalization, the core search team was under 100 people. It's probably larger now, but nowhere near the size of the sales organization.
What's the relevance of the ratio between engineers and sales people?
Seems the point you're making is that it takes 57,000+ people to make google run. You'd think they'd want to automate those sales reps, except that's human work and they can't. Which is the point the previous poster was trying to make.
Sales reps mostly talk to people and convince them to buy things. Relationships and human interaction are paramount.
I'm unwilling to speculate a couple of decades out when I don't think anybody has any clue what's going to happen in the next 5 years, forget decades.
But what I will say is this - there is no plausible way to automate human sales relationships in the foreseeable future. I don't even know of companies who are even seriously trying right now.
If you take the unbridled enthusiastic position that everything can be automated in 20 years, sure, all those sales guys are toast. I just don't see a pragmatic basis for taking that perspective. Tech gets better and that's great, but what you're talking about would be some Manhattan Project stuff. People have been talking about the potential of those advances since the 1960s. Wake me up when someone announces a date when they'll ship a product.
You don't have to replace sales relationships, you just eliminate them.
My life has become so much better with the advent of Amazon Prime and related services. I go to a website, find what I want, click a button, and whatever I want shows up on my doorstep two days later. It's fantastic, and nobody is trying to mislead me, or upsell me, or convince me to add on some shit that I really don't want. More things should be this easy.
