Rudranarayan Mukherjee, NASA JPL gave an update on progress to Robotic Assembly of Space Assets: Architectures and Technologies. This is the path to making 100 meter and even multi-kilometer diameter space telescopes and starshades in space.
The presentation was at the Future In-Space Operations (FISO) Working Group Presentations at the FISO telecon.
They are able to assemble 3-meter truss modules in the lab with robotic systems in 26 minutes
They have looked at sending robotic assembly systems to the space station and to have modular telescopes built in space.

To be fair, the first 3 items in your list (Botox, lip enhancements, Boobs) are about attracting a better mate. Those are fairly justifiable on a need to continue the species basis. Toenail arts could possibly be in there too for some subcultures. Valet parking? Like many services it has always struck me as taking longer and more effort to arrange the service* than it does to just do it yourself. I just don’t get the point. *I’m reminded of staying in a wealthy family’s guest house in India. The mixed Australian/Indian group walks in and we all decide we could do with a nice cup of tea. Indians go off in search of the servants while the Australians grab a kettle, pour water in it, and turn it on. Then we sit down and chat while the Indians are talking to the servants and telling them what they want. The servants are just getting around to actually start the tea preparation when our tea is finished and we start drinking. Having the servants do it took longer, more effort and there was a high chance they’d not give you exactly what you wanted. Likewise, valet parking requires you to 1. Queue up for valet parking 2. Make sure your car doesn’t have valuables easily stealable, while at the same time being presentable enough that you aren’t ashamed to have someone else in it. 3. Risk handing over your keys to some complete stranger 4. Queue up again to get the car back. 5. Then wait while they go and fetch it. 6. And they might scratch it or something.

The fun part is the design of the edge, to avoid diffracting in too much light. Which is why they’re sunflowers, not circular disks. All you need of the sun shade is positional stability, it’s the telescope using it that needs positional accuracy. Fortunately, it has the target star as a convenient reference.

If you want to do that, you need to go to independently flying mirror modules, with ultra-high precision station keeping. As telescopes get bigger, the physical structure becomes less and less effective at maintaining the shape anyway. Once it’s large enough that sound can’t make a round trip through the structure on the time frame you care about, it’s just a bunch of pieces flying in formation anyway. Skip the frame, and go straight to free flying modules, that can be added as you go without disturbing the rest.

Well, there you are. Starshades! Starshades are fun things, physics-wise. Basically, it is really straight-forward trigonometry that determines their dimensions. In essence, the fully-blocking (center of the sunflower arrangement) diameter needs to be 50% or so larger than minimally (trigonometrically) sized in order to block the full face of the remote star, with respect to the mirror at the shadow point. For instance, a star 10 parsec (32.6 LY) away, the size of Sol (1,391,000 km diameter) has an angular size of 4.51×10⁻⁹ radians. If my starshade is 100,000 km (¼ the way from earth to Moon) distant, it needs to be 0.43 × 2 or about 1 meter wider in diameter than the primary telescope mirror 100,000 km away. In turn, supposing that that starshade can be positioned within 1 meter accuracy (which is asking quite a bit), then plnets within 1 stellar radius and above might possibly be imaged directly. Just saying. Trigonometry. GoatGuy
