Re: 600 bots
It's being positioned that a single unit of 'bot' is equivalent or comparable to a human worker, but the measure of the chatbot software's capability is actually incredibly vague.
I'm not sure they are positioning it as such.
600 bots, 2600 people. Its very likely a single chat bot can replace whole call centers. In McDonalds they may need more screens as people are slower at ordering than staff were at entering them into the tills, but the cost of each screen is probably £2k so for the cost 1 staff member they can have at least 15 screens.
Good or bad for people depends on what you believe will happen next - scrap heap of life, or opportunity to get a better role. I expect there's no universal outcome......
