I don't mean that _all_ AI built stuff is useless, just that the number of products where 'marketing budget' is the bottleneck is dwarfed by the number of tools that aren't that special in the first place.
If you have a product that:
1. Solves a real problem people would pay for
2. Is not trivially replicable by your potential customers or competitors
3. Does not have a natural discovery mechanism by potential customers
Then you need the marketing budget.
That is not most people's problem.
