Our galaxy has ~10^70 atoms. At an atom per compute element, we will use 1/10^10 of our entire galaxy for our own compute? 10^60 is a bit more than the number of atoms in our sun. Given our sub-exponential space advances over the last 50 years, it seems... ambitious... to turn our sun into a computer in the next 300.
If they're saying we'll be an interstellar spacefaring civilization in much less than 300 years, they really buried their lead :)
So there are 1.2 x 10^57 atoms in the sun. And we need the sun.
The mismatch is caused by someone extrapolating an exponential trend in one area well into the future, ignoring physical reality. Anyone with a good grasp of high-school physics should have noticed this before the slides were released.

If you think we can't reach Kardashev scale I in 300 years you are really pessimistic!
We have, right now, the technology to go visit other stars. It would take a sizable amount of the world's GDP but it is possible. I certainly hope that in 300 years we will have explored other systems!
I'm not saying it's impossible, but I wouldn't trust these guys to do anything. The funding is basically all from one russian oligarch who probably does it for fun then gets board. Their last initiative was much less ambitious, yet after several years the website just says "Details of the competition will be announced soon."
