JWST has something like 300 SPOFs in the deployment phase. Then there are operation issues; the MIRI cryocooler has had a long, troubled development history. Three weeks ago NASA put out a Hollywood production quality disclaimer video[1]. [1] [this video]

I wonder if there are some aliens looking at this, and wondering if another advanced civilization has put this together (just like we were wondering with ʻOumuamua). To me James Webb looks definitely like alien technology, if it manages to pass 50 deployment stages, depending on 178 deployment mechanisms... The team working on this did an incredible job!

Critical shantara · 2021-11 · on “An “incident” with the James Webb Space Telescope has occurred”

After watching an official JWST video [this video] , they seem almost proud of having several hundred of single points of failure and an immensely complex deployment process that takes several weeks and must work perfectly. I don't know what engineer could be proud of coming up with a design like that.
