Apple is developing artificial intelligence (AI) software to power self-driving cars.

In a recent interview with Bloomberg, Apple CEO Tim Cook confirmed the company has been working on an Apple Car. While this is not the first time Apple talked about working on breaking into the car industry, it is a clear sign that Apple is expanding their reach in the tech industry.

Cook described Apple’s car project as a culmination of three different aspects including self-driving cars, electric vehicles, and ride-sharing. Together, those three factors could make the automobile industry even bigger.

That said, Cook says Apple is more focused on self-driving technology and not building a car.

“We’re focusing on… what we talked about we’re focusing on publicly is… We’re focusing on autonomous systems,” he said.

This interview confirms previous reports that the company has been focusing on building the software instead of manufacturing cars.

“Clearly, one purpose of autonomous systems is self-driving cars — there are others. And we sort of see it as the mother all AI projects,” Cook said to Bloomberg.

Cook added, “It’s probably one of the most difficult AI projects to work on. So autonomy is something that is incredibly exciting for us. But we’ll see where it takes us — we’re not really saying from a product point of view what we’ll do. It’s a core technology that we view as very important.”

It is important to note Apple received an autonomous vehicle test permit so that the company could start testing self-driving cars in California. So far, reports show Apple has been using a Lexus SUV to check their sensors and devices.

But, is it too late? Google has already released their self-driving technology company Waymo. In fact, on Monday Google’s Waymo retired their self-driving cars in favor of Minivans.

Apple has released a new revenue stream that could unleash a new community of digital content creators, which is already thriving in China.

Apple’s new update to their App Store policies official allows voluntary tipping via virtual currency as in-app purchases that Apple taxes by 30 percent. By taking tipping out of the company’s gray area, app developers may include a digital tip jar as a way to get content creators paid without having to offer ad revenue sharing.

Chinese live-streaming apps such as Yinke and Yizhibo have embraced the tipping model, which allows users to tip or send virtual gifts to people in exchange for extra attention. American live-streaming currently do not provide tipping. In fact, both Facebook Live and Periscope do not offer tipping.

It is important to note that Apple cracked down on unofficial tipping, which was a way around the 30 percent fee on in-app purchases by highlighting how the tips were donations rather than actual purchases. According to the Wall Street Journal, Apple told Chinese social media apps to disable their tipping functions or be kicked out of the company’s app store.

Apple did not have a rule in place about how tipping was classified. Now, the company has implemented a legitimate way to tip. As part of the company’s App Store policy update, Apple explains, “Apps may use in-app purchase currencies to enable customers to “tip” digital content providers in the app.”

This means developers can add tipping features without worrying about getting kicked out of the app store, as long as they are willing to give Apple 30%. As a result, entertainers and more content creators can make more money or even create higher quality digital content. As long as they are okay with Apple taking 30%.
