I don't buy that this is the last market. The current major one, yes, but calling it the last one is, not to be rude, short-sighted and unimaginative. AI/LLMs/advance algorithms will continue and some advanced technology will be built off of those. We didn't stop with plain electricity, we didn't stop with physical memory, we didn't stop with plain programs, so why would we stop now?

There are plenty of markets outside this one niche of "tech". And I get it, I'm the outsider in the fediverse as I don't work in IT, don't code, and don't even use Linux.

I work in American rail transportation (a notably hot topic here!) and it's incredibly outdated. Freight has such unimaginable interchangeability of individual cars between trains (consists) and rail lines that any kind of change has to overcome massive, disconnected lethargy of multiple groups. Aside from the shear volume of cars, it has to pass through multiple parties to operate on "interchange": all involved railroads, the car owners, the car leasees, sometimes the good owner, and the locomotive owner (not always the rail owner). Freight cars have no mandatory/universal electronics on board. Brakes are applied via manual air pressure logic from a single signal hose and can take several minutes to reach the end of the train. Certainly, wireless electronic communication would improve this but imagine trying to pair 250 cars to the locomotive. We can say just add a plug like a truck trailer plug, but changing a 100 year old hookup procedure is a task, so say the least. Improvement is coming, but adoption must be rolled out and it must be free of tamper risk. There's also essentially no tracking on rail cars. Services offered are atrocious. For maintenance, the latest thing is massive photobooths capturing every single car passing through. They're pretty effective. And, despite all this sounding ancient, hostile takeovers, planted execs, pleasing shareholders, and running logistics into the ground for a short profit return to shares is just as present.

Side note: the only "unit trains" around, the only ones that stay as one single consist and don't exchange between locomotives or rail lines, are coal trains. And they're on their way out.

Passenger trains leave much to be desired and while there's plenty of tech left to import from other continents, there's not much incentive. The USA is huge and the populations centers are far apart. We like to look at Germany, the UK, France, and the like as examples but their physical size is comparable to the US regions already served by transit. The US population is much more coastal than Europe (Atlantic, pacific, golf of Mexico, great lakes) and, on many topics really, Americans tend to forget about eastern Europe. That's our Midwest/rust belt/flyover states.

Road vehicles are ever-Improving but all I see here on lemmy is treating the privacy element as a crisis. I agree, and I can see why it's important, but the physical advances are blatantly ignored. Hybrid and bev have large hurdles ahead of them to continue mass adoption. Aerodynamics and other rolling resistance elements are always improved. Who knows what the next paradigm shift in cars will be.

Similar things apply to planes.

Building infrastructure is always advancing. Better insulation, faster construction techniques, stronger materials, longer spans, less foundation intrusion, and greater durability.

And yes, we can talk about the continuous enshittification of all these industries, but, just like tech, that's enshittification of the final product, not of the actual tech behind it. The tech has always been improving.

100%, all of this.

That's what happened for Personal Computers because most people could own one. Microsoft is trying to relive their PC highlights by going all in on nuclear powered mainframes.
