Why is it important to uncap budgets to fully capture the benefits of Google’s AI?

Google’s AI will only work in newly created campaigns with budgets of $1,000 per day or more.
Campaigns that adopt Google’s AI spend more money to reach more customers.
A Smart Bidding strategy will revert to manual bidding when a campaign’s budget is limited.
Campaigns need sufficient budget headroom to allow Google’s AI to work to its fullest potential.

The correct answer is:

Campaigns need sufficient budget headroom to allow Google’s AI to work to its fullest potential.
