Emma Walsh here, managing editor of the Journal. Routine Diary readers understand that tech isn't our normal beat. And when it comes to tech investing, we leave it to the experts. Thankfully, we have several such professionals in our Rolodex. Our coworker Jeff Brown will be familiar to our long time readers.
In fact, he had numerous triple-digit returns in his Brownstone Research study portfolios last year. Here's what Jeff thinks the tech sector will bring us in 2021 Each year, I like to have a look at the huge photo and forecast what's simply around the corner. Long time readers of my work know that I follow the most interesting tech trends on the verge of mass adoption.
These trends are experiencing rapid growth and developing extraordinary chances for financiers. 5G Devices Our brand-new 5G (fifth-generation) wireless networks are a subject I have actually been covering for years now.
Even though the COVID-19 pandemic disrupted supply chains in 2015, an impressive 250 million 5G-enabled devices were still sold. Specifically in the second quarter, there were supply chain interruptions, producing hold-ups, and work interruptions. And all of this eventually resulted in Apple delaying the release of the 5G-enabled i, Phone 12 by 2 months.
When you think about all of that, offering 250 million systems is remarkable. More notably, the delays caused by the pandemic produced a lot of pent-up need. And that demand is now going to be pushed into 2021. In fact, I predict that more than 500 million 5G devices will be shipped in 2021.
Stage Three of 5G When I've discussed 5G in the past, I have actually explained its three various stages. In Stage One, the facilities of these brand-new networks is constructed out, consisting of all the brand-new towers and fiber-optic electrical wiring that 5G will require. In Stage Two, 5G gadgets go on sale.
And in Stage Three, 5G services begin to be provided. That's when we start to see applications working on 5G networks. Think about 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 Stage 3 by this summer season.
More and more customers will go out to buy a 5G phone to access these applications. 5G is going to open up a suite of amazing applications: self-driving cars and trucks, the Web of Things, robotic surgical treatment, and more.
The financial investment chances going forward will be enormous. CRISPR Genetic Editing Stepping away from 5G, the next important innovation I anticipate in 2021 is CRISPR genetic editing. It's one of the most exciting developments in biotechnology.
