Most people in the economy do not use Slack. That tool may be most beneficial to those people who stand to lose jobs to AI displacement. Maybe after everyone is pink-slipped for an LLM or AI chatbot tool the total cost to the employer is reduced enough that they are willing to spend part of the money they saved eliminating warm bodies on AI tools and willing to pay a higher per employee price.

I think with a smaller employee pool though it is unlikely that it all evens out without the AI providers holding the users hostage for quarterly profits' sake.
