Write a 2,000-word formal academic paper (in IEEE two-column format and referencing style) discussing essential technological features of the TS and the various ways in which different futurists conceive it.

You should also discuss the current, emerging and future technologies that may be driving us towards the TS, as well as potential obstacles to prevent it.
