In the Netherlands it is not just about AI datacenters, even before the rise of AI pushback against Meta's planned datacenter made them cancel it. There has been a lot of criticism of the municipality that allowed Microsoft to expand its datacenters. The argument is that this is a small country that already has to make tradeoffs to get to its desired energy mix (wind turbines near cities on land) and then these datacenters are built that consume the power that is generated by sacrificing the little remaining open space. In the last few years there is actually a electricity shortage in some regions so "we can hook up this 200 MW datacenter but not your house" is a bad look.
Most "cyclists" are now actually drivers of light electric motorcycles. A $1500 Chinese ebike will do that easily.
Some engines maybe. Your average 1.5 TFSI is the equivalent of drawing corporate memphis clipart for a paycheck, no one is pouring their passion into that. Maybe not so bad if it gets replaced by an EV/AI.
ESMC should be online in a few years with 16nm class ICs. That will be tech that's over a decade old at that point but it's also "good enough" for anything except AI training.
7.8 km/s delta-v, that's quite a lot.
>You're also mysteriously adding in build cost for starship, and not the train. Starship is reusable.
Even if both are reusable a train will last decades and a starship will be lucky to get a few dozen launches, which is still amazing mind you. Maybe it is my lack of imagination but i just can't see how a diesel engine that pulls a metal box at 60mph will cost more per trip than a rocket that has to accelerate to 18000 mph. Even just fueling: a train runs on diesel which is easy to handle and everywhere. Starship requires cryogenic fuel and oxidizer which is inherently more difficult to handle.
So in this world vision obviously companies will start shipping iron ore and coal by starship from one coast to the other because it will be cheaper than trains. In fact all trucking worldwide would be replaced by space ships because they would be cheaper than trucks by far. I can't see how it will ever be cheaper to build a literal space ship and launch it than to put stuff on a train. This all reads like some super optimistic early 50's scifi.
