Artificial intelligence was supposed to make life easier for all of us. In the case of robocalls—those persistent, indefatigable automated dialers that pester millions of people with often-bogus sales offers—it’s proving to be one of our biggest nuisances. Somehow, we’re powerless to stop them.

According to a recent NBC News report by Nigel Chiwaya and Jeremia Kimelman, they’re now worse than ever. NBC cited data from YouMail, a voicemail and call-blocking service for iPhone and Android customers, that demonstrated a staggering increase in robocalls: Americans received in excess of 4 billion of the calls in June 2018, up from more than 2 billion in January 2016. Telemarketing calls also topped the list of consumer complaints filed with the Federal Communications Commission (FCC).

How frequently you’re interrupted by these calls may depend on your region. Residents of Atlanta received an average of 68 robocalls in September. Those with a 202 area code in Washington, D.C. got 49 calls. On average, a U.S. resident can expect to receive 13 robocalls a month.

There are two possible reasons for the uptick in the calls. Phone apps that block unwanted or unfamiliar numbers are increasing in popularity, which may be prompting scammers and telemarketers to make more calls in an effort to get through. It’s also easier than ever to dispatch the calls, as new software programs make it a snap for anyone to set up a system to mass-dial potential customers. The effort is so cheap—sometimes pennies per call—that if even a small percentage of people respond, it’s worth the investment.

According to CBS News, 25 million Americans were drawn in by a pitch of this type last year alone, losing $9 billion to scams. (“Spoofing,” which can display a local number on a person’s caller ID function, can be an effective way to get an individual to answer the phone.)

What’s the FCC doing about it? This year, they’ve suggested multimillion dollar fines for companies targeting people with robocalls that use spoof numbers. That may deter domestic companies, but because many robocallers are located outside of the United States, it might not lead to a drastic reduction in the number of calls.

There was also hope that the National Do Not Call Registry, which allows consumers to request their number not be dialed by businesses, would lessen the volume. Unfortunately, law-abiding businesses make up only a fraction of those making the calls.

Industry experts have drawn comparisons to spam emails, citing the wave of unsolicited messages that blanketed the internet in the early 2000s before services were able to funnel them out of view. The same may hold true for phone carriers. AT&T offers Call Protect, a service that tries to caution users when an incoming call might be dubious. T-Mobile has Scam Block, which keeps an inventory of known scam numbers so it can block them from coming in.

For now, the best thing consumers can do is ignore calls from unknown numbers and hope technology—like Google’s Pixel smartphone, which will answer and transcribe calls for review, or Stir/Shaken, a cross-platform standard that might one day authenticate phone numbers—will be able to stem the tide of unwanted calls.

Unfortunately, the robocall epidemic could get worse before it gets better. It's being predicted that by 2019, half of all incoming cell phone calls will be from a non-human.
