So, gentleman, if you had a general autonomous superintelligence at your disposal, what would you want it to do?"
Hitler: "I'd want it to kill all the Jews... and humble France... and crush communism... and give a rebirth to the glory of all the beloved Germanic people... and cure our blond blue eyed (plus me) glorious Aryan nation of the corruption of lesser brown-eyed races (except for me)... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and..."
Gandhi: "I'd want it to convince the British to grant Indian independence... and overturn the cast system... and cause people of different colours to value and respect one another... and grant self-sustaining livelihoods to all the poor and oppressed of this world... and purge violence from the heart of men... and reconcile religions... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and... and..."

Hitler and Gandhi together: "Stay inside the box and answer questions accurately".
Probably slightly. Most likely we will get machine intelligence before nanotech and good robots. To build an e-brain you just need a nanotech NAND gate. It is easier to build a brain than an ecosystem. Some lament the difficulties of software engineering - but their concerns seem rather overrated . Yes, software lags behind hardware - but not by a huge amount.
That seems rather pessimistic to me.
The "convergence" I mentioned also includes robots and biotechnology. That should take out any other examples you might have been thinking of.
