- Complete GuileMacs, the Guile implementation of Emacs. As AI is supposedly much more capable than Humans, it would be great if the above mentioned implementations are even more efficient and feature rich than Emacs!

- Something like Android (maybe even a clone?) with the Java Layer removed and replaced with CL and with Linux kernel still intact. Basically CL over Linux as opposed to the Java over Linux in Android.

- For fun, an implementation of the Lisp machines' OS with Lisp all the way down though Assembly is allowed for critical pieces. It should be a full blown modern Desktop with equivalents of what users expect from a modern OS ...

Even in otherwise (mentally) healthy people such accidents happen with some regularity but with the history of this particular illness afflicting him and the nature of the incident (walking away and then turning back before impact) makes the police's statement sounds dismissive and reckless at best and a coverup for the train company and/or avoidance of some significant workload (investigation of an avoidable death by train company vs a suicide of a mentally ill person) for themselves.

People with such illnesses typically hear voices and at any given time they could be engaged in a rather deep conversation with them(selves). Even if he was not listening to music and such or was otherwise distracted by something else it would not be surprising for a person of his illness to not being able to hear the train approaching. When he finally heard it, he apparently did turn but it was - unfortunately - too late.

Someone with more insight into the manner of train suicides would hopefully weigh in with more informed opinion but as far as I understand the typical way is to jump (not always literally) in front of the train.

Simply walking away from the train provides ample opportunity for an alert driver to stop or slow the train both of which are undesirable for the suicidal person and one (the slow train running over you) could be much worse than the other options.

Rather it seems the train driver failed (some one with more technical train knowledge would correct me here if there are some other reasons for not applying brakes in train even after seeing an - apparently - oblivious man walking away from the train) to stop the train in time and prevent an avoidable death.

I could be wrong but there is the possibility that it would be much desirable for the train company and easier (given the history of his illness) for the authorities to dismiss his death as suicide rather than hold the person(s) responsible for the accident accountable for their actions.

Way to go! Replying to the grand parent's (revelation's) solid argument by using vague statements. Just what does the most famous living constitutional law scholar even mean? Besides being meaningless statement like the most beautiful woman in the world it is also almost irrelevant - almost nonsensical - to the current discussion. Just because a person has had a successful career - particularly in politics, bureaucracy and fields like that - doesn't mean the person doesn't have an agenda and vested interest. In fact some would argue it is quite the opposite as - unlike some tech/hard science luminaries, for example - their success is likely correlated with their other - rather nefarious - traits than pure merit alone.

Your next paragraph about Richard Clarke is in similar vein.

It seems disingenuous to have the achievements of those companies be co-opted by/as Google/'s
