afaik the current limitations with plasma torch garbage disposal is not the power, but the plasma degrades the materials making up the furnace too quickly. If the input is general waste then the process produces as much energy as it takes. It needs energy to start or if the input doesn't have enough hydrocarbons.

Except some crashes are impossible to prevent. There will be some ambulance chasers that try to cash in on these crashes, regardless of whose fault it actually is. A likely outcome is that the lawyers trying to get money from autonomous car makers will change the question from "whose fault was it?" to "Why didn't your car prevent the crash?". Even if none of the lawyers win, the makers still have to spend a lot of money defending themselves.

One thing I didn't understand about the Deus Ex world was their inability to hide augmentations. A lot of prejudice could have been stopped if augmentations were more discreet.
Also most of the social problems could have been reduced if the anti-rejection drug, neroprozine wasn't sold at aubsurd prices.

It's more like this:
The objective of the BART group is to run the trains, safely and on schedule.
A train station is a dangerous place during a protest. Protests, being large relatively immobile crowds have the possibility of pushing people into places where they shouldn't be. Between an enclosed space causing crush problems, the electrical lines for the trains, and the trains themselves, I wouldn't want to be in a train station during a protest.

Probably they decided to shut down the stations for two reasons: So that nobody would get hurt (which would then be blamed on BART's response) and so that hopefully the protesters would get bored and leave sooner so they could resume service.

They had to trim it to get it to fit in the lunar lander...

Well they can blow up conventionally. Chernobyl exploded because the reactor's graphite moderation rods caught fire and the uranium fuel produced so much heat that the structures covering the reactor became pressure vessels and exploded.
Chernobyl didn't have a massive containment building like all western reactors do.

Unless you're planning to visit the nuclear plants themselves, it won't affect anything. The Fukushima Daiichi plant is 250km away from Tokyo.

Not really, middle of Tokyo has a ridiculous population density but the more rural regions have a relatively low population density.

You're giving the computer too much credit. The choice that the computer makes is dependent on how it was programmed. No computer at the application level is purely logical.
An AI isn't going to be driving your car, an automated driving program is. The driving program won't even consider your worth compared to the 7-year old. It's likely that it will be programmed to chose paths which will cause the least damage while prioritizing some types of damage.

Having an AI driving your car is silly, I don't want my car to have an existential crisis while on the freeway. Having an automated driving program driving a car would be fantastic.

Cells are cancerous, but virii can cause a cell to be cancerous. A virus itself cannot be cancerous, because it cannot reproduce alone. More importantly, this magical technique can tell the difference between a healthy cell and a cancerous cell, which might only be two or three switched genes out of trillions? And this will work over my entire body, despite any reflection and other interference?
Virii are a bit more believable, but still, the difference between two virii could be only a single gene swap.

Maybe the reason he was discredited was because it didn't work?
Considering this technique could wipe out all viral, bacterial and fungal infections, as well as all cancers... I'm inclined to believe that it didn't work.
