<P> Brown University computer scientist Michael Littman has argued that successful execution of the Internet of things requires consideration of the interface's usability as well as the technology itself . These interfaces need to be not only more user - friendly but also better integrated: "If users need to learn different interfaces for their vacuums, their locks, their sprinklers, their lights, and their coffeemakers, it's tough to say that their lives have been made any easier ." </P> <Table> <Tr> <Td> </Td> <Td> This section does not cite any sources .

Modern electronics are replete with a wide variety of heavy metals and rare - earth metals, as well as highly toxic synthetic chemicals . This makes them extremely difficult to properly recycle . Electronic components are often incinerated or placed in regular landfills . Furthermore, the human and environmental cost of mining the rare - earth metals that are integral to modern electronic components continues to grow . With production of electronic equipment growing globally yet little of the metals (from end - of - life equipment) are being recovered for reuse, the environmental impacts can be expected to increase . </P>
