A.s.a. H. question generation

 If A.s.a. generates an output signal that is too weak it will be unable to drive its effector (motor, servo, etc.). But if the output signal is above some preset threshold it can, instead, trigger a question, e.g., "should the xxxxxxx  effector be triggered?" Bystanders may then respond or ignore the question as they see fit. 

An issue with LLM generated computer code

 It is my impression* that LLM generated code requires more debugging as compared to my hand written code. I think most of us hate debugging. Especially debugging other people's code.

* I admit that I don't have enough experience to quantify this impression.



On the simulation hypothesis

First and foremost I am my mind. Our best current model says that my thoughts are electrochemical signals in a biological brain*. The simulation hypothesis would have me be signals (electrical?) in a vast computer. This doesn't seem any less "real". We've already been adding lots of layers to our models of reality*.

* Or, at a deeper level, quantum fields and the like?

Rocket recovery and reuse

For every pound you must invest in the heat shield for the recoverable rocket's orbital* stage you will lose one pound of payload. Does it make sense then to recover simple tankage? Perhaps one should only recover the engines, pumps, and avionics. I.e., something like** ULA's "SMART" but applied to the upper stage***.

* typically second stage 

** may or may not use inflatable heat shield

*** or think drop tanks

Is mathematics invented or discovered?

 I was not trained as a mathematician so perhaps I should keep this to myself but I am going to answer in one word: YES. By that I mean that I think some of math is invented and some of it is discovered*. I suppose that one might first think about what mathematics is. Again, as a non expert my view has been that mathematics is: 1. A science of patterns. 2. A language. 3. A game. When I use mathematics to talk about patterns I see in nature I have discovered things about those patterns. Perhaps I describe mechanics using Newton's laws of motion and then discover recurrence phenomena. If, on the other hand, I am creative and extrapolate I may be able to create mathematics that has no parallel in the natural world. In that case I have invented something, perhaps new concepts** that I will later use in my languages.

* Wikipedia says most philosophers of mathematics believe that mathematics is discovered rather than invented.

** One of the longterm goals of A.s.a. H. is to invent new and useful concepts with which to think (new or old thoughts).

Python vs C

 I have not quantified the differences but for a couple of my A.I. robotics experiments Python proved to be too slow and I had to switch over to C.

A.s.a. hardware upgrade

 In the last week I have built up a new computer system with a clock speed of 5-6 GHz, 14 cores, 64 GB of RAM, 2 TB of internal SSD, and many TB of external memory. I did an A.s.a. H. extrapolation/creativity experiment to try it out.
