Fascinating video, but honestly the only thought that kept going through my head is: they've overcomplicated this.

Despite it's impressive number of steps, this does not look like good engineering.

Instead, it looks like a design by committee, with engineers going drunk on complex parts coming together rather than dumbing down the unfurling of this telescope down to its most basic possible mechanism, with the fewest moving parts possible (where failure is chronically always possible).

Seeing how overcomplicated this is, it's no surprise it cost $10 billion to build.
