This is called a 'plotter', there's a whole community of axi-draw enthusiasts making cool art, for 200 bones you can probably have one on your doorstep tomorrow
It’s not obvious to me that a “nobody wants this” megaproject by a decades old multinational forced to succeed by government mandate wasting over a decade debating national workshare is a great example of a “startup in aerospace”.
There’s tons of startups making cool fused harnesses and phased arrays and trying to get every permutation of diesel and electric and hydrogen engines certified. Drones and rc aircraft spawn many “built in a dorm room” prototypes for people who don’t value their eyebrows

It looks like I wrote that in a confusing way! My intention was to ask about what features of the engineering discipline was motivating OP's comparison. Maybe a better series of comparisons would have been...
- the 747 – program conception in '63, delivery in '69;
– the A350 - first sales in '05, delivery in '13;
which I think captures the slow pace, and large dependency chain, of any significant program beyond a revision.
We already have 25kV for rail electrification which move 6MW all over the place, surely at boat speeds making some strange double-pantograph system for shipping could be strung up alongside most of the canals, maybe electric tugs could be used as well as normal shipping?

I like it, very similar to how mules used to pull barges thru canals except with electrical cables and a rail pantograph running on distribution lines next to the canal instead of mules and ropes.
703 nm laser is almost “loo”, and 417 nm is almost “ool”. Searching those wavelengths gives me #FF0000 and #6400FF. Loo is all red and ool is all violet.
The correct solution is just giving people the option to charge people for phoning them.
Say minimum wage is 12euro/hour, and declining a call takes about a minute of your attention, so this is worth at least 20cent.
Instead of just "Answer" and "Hang-Up", there should be a gov't enforced "charge caller 20cent" option.
This would have no impact on 'real' calls, nobody would charge their Mother and if someone is tacky enough to charge their GP or mechanic they could just be billed for it, and it would hardly be worth someone's trouble to try to steal a phone to call themselves to collect 20c, but it would totally ruin the economics of these spam calls.
There a story, perhaps apochraphal, from 15 years ago of a man setting up a premium rate line and getting paid whenever telemarketers called him. I believe the phone service said anyone doing that would be fined because you need to inform potential callers it's a premium rate number
impressively convoluted. Spam calls are coming from all over the world using voip and prepaid sims. There aren't any accounts to "bill". Not to mention a whole new arena for fraud in spoofing regular numbers for micropayments
To end up on your phone, VOIP have to terminate somewhere in local phone network. These networks need to stop accepting calls from shady places, or every call like this that they cannot charge back to original (or intermediary network) becomes a loss to them. And telecom companies do not like losses...
