Steve Jobs biographer Walter Issacson has some harsh words for the tech giant Apple: Google is out innovating you.

The famous biographer — who was granted an unprecedented level of access to Jobs’ tech empire — says Google is leading the way when it comes to innovating.

Speaking in an interview with CNBC, Issacson slammed Apple, saying it has fallen behind the search giant, and it has lost its way. The biographer cited the recent acquisition of Nest by Google this week, saying the buyout represents a move by Google to infiltrate every device consumers interact with.

“Google buying Nest shows an amazingly strong, integrated strategy that Google has to connect all of our devices, all of our lives … the Internet of things is actually real, there are these devices we’re gonna want to have and Google’s going to get ahead of that game,” Isaacson said during an interview with CNBC.

While Google’s recent acquisition raised some eyebrows within the world of tech, some have warned not to count out Apple. The company has long made it policy not to discuss future project, and some have noted that Apple may already have a similar device in the works.

Still, Issacson pointed to a number of recent Google deals, saying the tech giant remains a major player in the world of telecommunications. Citing a recent deal inked with China Mobile — the largest wireless carrier in the world — Issacson said Google could eventually bump Apple out of growing markets in Africa and in China. Apple’s Tim Cook has openly expressed interest in capturing a larger share of the Chinese market, and has pushed for the release of a number of lower priced iPhones.

In 2001, Apple really defined themselves with the iPod and iTunes and forever changed the way we purchase and listen to music.  Following the stunning success of the iPod and iTunes, Apple launched the iPad and rumors were abound of the company moving into the world of television before Jobs’ death two years ago.  Since Jobs’ death, investors have long worried the tech giant would struggle to develop new devices that draw consumers back to its stores.
