Investors want a "bionic" financial advisor who offers a low-cost, automated investing platform paired with patient, personal advice, according to a new survey by the Financial Planning Association and Investopedia.

Among people using automated investing services, known as robo-advisors, 73 percent were satisfied with their experience, the survey found. Meanwhile, 75 percent of people who primarily work with a financial advisor said they were pleased.

"The debate about whether robos or human advisors will win is moot," said Investopedia CEO David Siegel in a statement. "The future of financial advice is bionic — a powerful combination of both." While people who used robo-advisors were generally satisfied, 40 percent of those surveyed said they were uncomfortable using the services during periods of extreme market volatility. The Financial Planning Association and Investopedia surveyed 2,002 U.S. investors age 21 or older in August and September about their preferences for planning advice.
