Which makes me wonder what search network ads look like in a hypothetical world in not so distant future if audio interfaces were primary search tool and output

Which makes me wonder what search network ads look like in a hypothetical world in not so distant future if audio interfaces were primary search tool and output for the results. Personally, at this point I'd rather pay Google a monthly subscription and get everything ad-free. That would align their interests with their users who would then be the customers vs the product and free up Google to do what is best for them in cases where ads may not make sense.
