The billionaire businessman, appearing on Megyn Kelly's Fox Business show the same night, called for both presumptive presidential candidates to do more than just say "This is bad."
Cuban proposed that the country look to technological innovations for a solution. Among other ideas, he would turn to automation and robotics.
"How do you deal with immigration? How do you deal with radical Islamic terrorists trying to come into the country? You're going to need to use tech," said Cuban, in a Bloomberg interview earlier this week.
Both the Republican and Democrat would-be nominees are technologically illiterate, he said to Bloomberg's Cory Johnson, which is the reason they are blind to technological solutions to the country's biggest issues.
"I am a tech guy," Cuban continued, "I've invested in companies that allow for, and create the ability to test and evaluate people before they come in." The billionaire explained that he has invested in artificial intelligence firm Converus, whose lie-detecting technology can tell with 85 percent accuracy whether or not you'll be a threat to national security.
The technology's high level of accuracy is possible because it takes out the human error of conventional polygraphs, according to Converus CEO Todd Mickelsen. And the degree of confidence can increase to more than 98 percent when combined with a secondary method, he adds.
"There are tools available for vetting terrorists that are not being taken advantage of," Mickelsen tells Inc. "Why not apply a different technological solution?" The tool might be particularly useful in cases involving refugees or other situations where little background data is available, the tech CEO says. "Why not leverage the best database available--the human mind of the individual--and ask them the same questions you're asking them anyway but on a computer?"
Cuban is convinced that Converus's EyeDetect, which allows for optical scanning, would be instrumental for immigration and as a potential terror warning system. Earlier this month, Cuban tweeted about use of the tool to identify possible terrorist suspects among Syrian refugees:

And later, he posed the question:
Cuban has also previously stated his support for legal immigration and open, international competition for talent. In an interview with Fox Business last fall, he said: "When it comes to high-end jobs, the competition from overseas for jobs makes us stronger."
It is a position that puts him at odds with presumptive Republican nominee Donald Trump. The presidential candidate proposes protecting American businesses and jobs against foreign competition through measures such as increasing the wage requirements for H-1B work visa holders (in addition to his now infamous huge wall).
But Cuban holds that isolation is not an alternative. "Voting for 'no' is never a solution for much of anything," he said Tuesday, explaining that, as shown by the Brexit vote, it usually leads to confusion and uncertainty. "Confusion and uncertainty is always bad for business and is always bad for markets."
