With the rise of central hubs like Alexa, Siri and Home, all devices can be combined into one big network and control and respond to each other.
The biggest concern with IoT is security: how do we prevent someone with bad intentions to gain access to devices in my home or office, or -- even worse -- my wearables? As with all new technology, the answer is simple: this will take time. There are a lot of small and large players on the IoT market working on privacy-first systems, it just takes time before standards are developed.
Another point of criticism: why do we need this? The answer to this is also very simple: these steps are not so much necessary, as much as these steps are simply the logical next steps in using electronics around us.
We love to work on IoT projects, where for us the challenge is mostly designing and developing a comfortable, logical and easy-to-use user interface. Our knowledge on hardware helps us translate functionality for our end users.
