Imagine having your own self-contained knowledge manipulator in a portable package the size andshape of an ordinary notebook. How would you use it if it had enough power to outrace yoursenses of sight and hearing, enough capacity to store for later retrieval thousands of page-equivalentsof reference materials, poems, letters, recipes, drawings, animations, musical scores, waveforms,dynamic simulations, and anything else you would like to create, remember, and change?
Fascinating how Even though we did realized some of this with the mobile phone we still have a system that's so fragmented that it's fundamentally getting in the way of progress

Mobile Network Hacking, IP Edition. by Karsten Nohl, Luca Melette & Sina Yazdanmehr. Black Hat. London. December 2-5, 2019. 47 minute video. https://www.blackhat.com/eu-19/briefings/schedule/index.html#mobile-network-hacking-ip-edition-17617
Mobile networks have gone through a decade of security improvements ranging from better GSM encryption to stronger SIM card and SS7 configurations. These improvements were driven by research at this and other hacking conferences.
Meanwhile, the networks have also mushroomed in complexity by integrating an ever-growing number of IT technologies from SIP to WiFi, IPSec, and most notably web technologies.
This talk illustrates the security shortcomings when merging IT protocols into mobile networks. We bring back hacking gadgets long thought to be mitigated, including intercepting IMSI catchers, remote SMS intercept, and universal caller ID spoofing.
We explore which protection measures are missing from the mobile network and discuss how to best bring them over from the IT security domain into mobile networks.

The definition of “super app” is fuzzy, but companies and their leaders most often use it to describe a state of cramming ever more features and functions into their apps—often ones adjacent to, but distinct from, their core functionality. So, for example, a financial-tech super app might start with payments and bolt on buy-now-pay-later, cryptocurrency and in-app storefronts. For social media, it could mean incorporating things like shopping. And for a delivery and ride-hailing company, it might mean adding new modes of transportation or other categories of goods for drivers to convey.
Definition of "super-app"
Not yet common in the U.S., but exemplified by WeChat in China. This is a response to the decline in mobile app user tracking and the corresponding ad-tech. It is about capturing more time and attention from mobile computing uers.
