So companies, who've frequently gone for the cloud because they couldn't forecast what they needed on their own hardware, have used more than they intended....

Airborne software used to be really reliable, but was extremely expensive to create and test and dealt with a much simpler environment. Even so, it used to be subject to massive regulation and certification. Recent events show what happens when that process is 'streamlined' to save money through cheaper dev/test and/or reduced or sub-contracted certification.
What on earth do we think will happen when this sort of (much much more complicated) software gets developed for cars which are relatively cheap, more loosely regulated and developed by companies that focus on saving pennies on their multi-thousand pound products?
Aircraft software (airborne software) is documented to death, written in one of a few certified compilers, walked through and tested to death. It runs on old, very well understood processors and is generally pretty simple - look up tables with simple interpolation algorithms. All the data is developed on the ground, slowly, carefully and under a microscope. There are more than one of everything in the plane and if they disagree, they shut down and the pilot takes over. Yes the results are clever, but the implementation is clear. It is written for one type of aircraft at a time. AND IT IS VERY VERY EXPENSIVE!!!!!
Compare to the above - state of the art hardware (Pentium FPU anyone...), Consumer O/S (enough said), commercial constraints and minimal regulation, Dozens of types and models of cars, brakes, engines, steering etc etc.
Its a bit like Mainframe vs PC - would you trust your life to a PC?
So, we're all skint, prices are going up - and the response is to.... up the interest rate and make everything even more expensive??? How does that work then? If people are borrowing tons of money and spending it on 'stuff' pushing up prices, I can see how an interest rate hike would slow things down - but I reckon if they only measured inflation on needed things (food, energy, fuel etc) the figure would be even worse - and that's not driven by consumer spending - so.... how's an interest rate going to do anything other than slow everything down?
My son plays simple platform games on Friv using a P4 3.2 with 2GB Ram. It maxes the CPU all the time - my old Amiga 500 could have done those half asleep. Trying to play HD video using iPlayer - it can't, and yet the same machine can play HD video using VLC/MediaPlayer with only 10% CPU thanks to a cheap HD grfx card.
Flash is pants, used by numpties to write crap code..... but cos everyone has it, it's the easy choice. Can it.
