Human Robot
‘Cyborg assistant’

Founded in 1996 204 office in 77 Employ 18 500 different countries World leaders connecting travellers](https://reader034.fdocuments.us/reader034/viewer/2022051808/600e52aca4c710502e0c7aaa/html5/thumbnails/18.jpg)
Why the Assistant needs humans.
True AI is still a long way away
Human-in-the-loop training is
constantly required to train the
assistant
The assistant is hungry for data
Even simple prediction models
need tens of thousands relevant,
clean and annotated data points
The assistant can’t think
It isn’t able to understand context
or accurately define intent
The assistant can be unpredictable
Even the most precise prediction
models make decisions that cannot
be understood fully
