Last year, a company named Nectome, "advetised" a service for backing up & (eventually) digitizing people's brains which was going to be 100%-fatal. They retracted saying it wasn't correct they expected to revive a whole consciousness from the connectome buff.ly/2YT1Eaq
The actual computational requirements for running an uploaded human mind are very difficult to quantify & strongly depend on the chosen level of simulation model scale. In other words, if you want a very precise copy, you need a ginormous processing power buff.ly/2G0UCYG
There is, however, a different approach to mind uploading that uses a completely different set of technologies: mind virtualisation, i.e. extracting a number of characteristics from a mind to develop a model that can be used to simulate future behaviour buff.ly/2KdpXg4
In 2015, a digital imitation of circuitry in a sandgrain-sized chunk of rat brain was realized. The work modeled some 31,000 virtual brain cells connected by roughly 37 million synapses ow.ly/Hmy230olJlN
In 2013, the European Union funded the Human Brain Project, led by Henry Markram, to the tune of $1.3 billion. Markram claimed that the project would create a simulation of the entire human brain on a supercomputer within a decade buff.ly/2uP5e7s

1⃣ Greenland is the world’s largest island that’s not a continent. It’s 3x Texas but 80% ice—2.85M sq km of frozen wildness. If that ice melts? Say goodbye to Florida.
2⃣ Greenland is big…but not THAT big. Thanks to the Mercator projection, on a map, it looks like it’s about the size of Africa or 3-4 times the size of Australia when, in fact, it is only one-fourteenth the size of the former and one-quarter the size of the latter.
3⃣ Population: 56,000. More polar bears (2,500) than towns (just 17). You’re more likely to meet a bear than a traffic jam.
