NASA Launches Twin Radiation Belt Storm Probes

I'm just wondering about length of time needed to build spacecraft. Is there a possibility of trying to develop full-on robot automated manufacturing of spacecraft to try and reduce cost and increase speed of manufacture? Or is it just that the current combination of no money up front, pushing the envelope, and needing human brainpower for testing and imagining failure modes? Are there any parts of spacecraft these days that are assembled robotically or is it 100% bespoke? Which is still cool but not space operaish yet. You see automated manufacturing attached to automated mining and supply lines means we can set up a remote site on the Moon or Mars.

Excepting very few use cases, most spacecraft are bespoke because each mission is different. There are very few times when a spacecraft is constructed en masse - basically the same spacecraft churned out in multiple copies, and even then the number tends to be extremely limited (usually below 10), so setting up assembly lines doesn't generally justify the overhead.

Now, there are efforts to componentize spacecraft so building one is basically like snapping together Lego. Including having flight software automatically reconfigure itself to handle those blocks like modern OSes do when you plug in USB devices.

The main problem is that it's extremely expensive to launch spacecraft - easily $1B per launch. Neverminding the large fraction that don't make it at all. As such, equipment sent up there has to put up with some of the worst scenarios in the world - little projectiles whizzing along and handling all the damage it causes, limited weight (too heavy and it costs way more $$$), the fact that there's no way to practically repair it (very few get the Hubble treatment), and that it has to last many years (because you don't want to launch its replacement and spend another billion soon aferwards)

When you've got billion(s) on the line, spending a few years ensuring that failures are minimized and tolerated is just part of the game. Cube sats and such only have to last a few weeks - which is a much easier thing to do than making one last at least a decade or more.
