Amazon.com is a business. AI is a technology in of itself it isn't a business.

Thus far it appears applications of AI that provide 'benefit' do so by removing or reducing the need for human operators. Examples include: fewer software engineers, fewer call centres, removing potentially whole areas of work such as paralegals and in general automating away many white collar jobs.

By far the largest use case of AI is this.

Internet is also not a business but it removed a lot of people but increased productivity and prosperity.
