Three decades ago, smartphones did not exist (the first phone of the "smart kind" was the Simon Personal Communicator, released in 1994,) while just over half a century ago (the first personal-use computer Altair was developed in 1974,) nobody had a computer in their home. Just let this sink in for a little. It feels like technology is accelerating at an immense pace.

According to Ray Kurzweil and his book “The Singularity Is Near,” technology’s quickening pace is not just a feeling, but actually real. It turns out, “the pace of technological progress—especially information technology—speeds up exponentially over time because there is a common force driving it forward.”

In other words, every generation of technology improves over the last as it achieves some kind of rate of progress.

When taking two separate innovations from different eras, from the birth of the first modern car in 1886 to the beginning of the self-driving car era in 2012, every step of progress speeds up from one version to the next.

The Singularity Hub explains that the more effective technology is, the more attention it receives, and the more efficient flow of new resources it has. “Increased R&D budgets, recruiting top talent, etc. are directed to further improving the technology.”

With that in mind, we can suspect that technological innovation will look very different in a couple of decades' time from now. It may not be the flying cars as we’ve seen in retro-futuristic movies, but it may well be an AI friend who talks to you like a real person. Oh, wait, we don’t need to wait that long, since that already exists.
