Re: Oh really ?
...IoT is a world of badly implemented useless or bad ideas.
So, IoT is a world of badly implemented useless ideas or badly implemented bad ideas.
Anything poorly implemented has the possibility to be really dangerous on the grounds that it has not been implemented according to specification.
It does depend on how one defines 'bad' and I assume the OP meant a poor implementation of an evil idea. I will admit that I'm not too worried, though, about poorly implemented evil ideas.
What a useless idea is, I'm not sure. Can ideas have no use?
