Could raise barriers because AI without a subscription service is not profitable, and competing with firms with monopolistic power such as OpenAI would be challenging
How may AI change the web browser market
It may shift the internet from a free and easily accessible platform, to a subscription based platform, as AI is not very profitable.
May shift the web browser market to a more profitable market with less competition and restricted access for consumers

Survival
What is meant by profit maximisation
When a firm seeks to make the largest positive difference between total revenue and total costs
What does making large profits enable firms to do

what may the objectives of directors be
Growth maximisation - to boost the profile and CV of senior managers
Sales revenue maximisation - executive pay and bonuses may be linked to annual sales revenue
Satisficing - firms are more able to target a satisfactory, suboptimal level of profit rather than a maximised one
What does satisficing mean
Making do with a satisfactory, suboptimal level of profit below profit
What is sales maximisation
Sales maximisation occurs at the level of output where the sale of one more unit would not add to total revenue, this can help the firm benefit from economies of scale
Survival (obj of firms)
A large proportion of new businesses fail in the first few years of operation
Therefore a key objective of a firm might simply be to survive the critical period before it establishes a customer base and sales
