Emma Walsh here, managing editor of the Diary. Regular Journal readers understand that tech isn't our normal beat. And when it comes to tech investing, we leave it to the specialists. Thankfully, we have numerous such experts in our Rolodex. Our colleague Jeff Brown will be familiar to our longtime readers.
In truth, he had numerous triple-digit returns in his Brownstone Research portfolios in 2015. Here's what Jeff believes the tech sector will bring us in 2021 Each year, I like to take a look at the big picture and predict what's just around the corner. Long time readers of my work know that I follow the most exciting tech trends on the verge of mass adoption.
These trends are experiencing exponential development and creating unbelievable chances for investors. 5G Gadgets Our brand-new 5G (fifth-generation) cordless networks are a subject I have actually been covering for years now.
Despite the fact that the COVID-19 pandemic interfered with supply chains in 2015, a remarkable 250 million 5G-enabled gadgets were still sold. Specifically in the second quarter, there were supply chain disruptions, producing delays, and work interruptions. And all of this eventually led to Apple delaying the release of the 5G-enabled i, Phone 12 by two months.
And that demand is now going to be pressed into 2021. I predict that more than 500 million 5G gadgets will be delivered in 2021.
Phase Three of 5G When I have actually discussed 5G in the past, I have actually explained its 3 different stages. In Phase One, the infrastructure of these brand-new networks is developed out, consisting of all the brand-new towers and fiber-optic electrical wiring that 5G will need. In Phase 2, 5G devices go on sale.
And in Phase 3, 5G services start to be provided. That's when we start to see applications operating on 5G networks. Think of things like massive multiplayer games over a smart phone. That's not possible with 4G. It will be with 5G. And my second 5G prediction for 2021 is that we will start Phase 3 by this summer season.
However they will care if there are interesting applications that can only be accessed with a 5G phone. So a growing number of customers will go out to buy a 5G phone to access these applications. That leads to more 5G apps being developed. In fact, 5G is going to open up a suite of extraordinary applications: self-driving vehicles, the Internet of Things, robotic surgical treatment, and more.
The financial investment chances going forward will be huge. CRISPR Genetic Editing Stepping away from 5G, the next important technology I predict in 2021 is CRISPR hereditary editing. It's one of the most exciting developments in biotechnology.
