As I hear, ARM at beginning was near pure educational chip, or toy for mature boys. MIPS grown on very different soil, it was from beginning pushed by business shark. Only much later, created ARM holding and they pushed ARM architecture to

This is not fair compare. Motorola and Intel that time outperforms first RISC machines, because have much better silicone level (even when logic level was not best). But game consoles are fair, as they was specialized machines, made with go

It depends. Exists few levels, to know exactly need more information. Mostly used in modern tech types 1 and 3a from my comment, but large scale production CPU SOCs usually 3b or hybrid 3b with 2, and sometimes you could found type 2 in con

“democracy is the worst form of government – except for all the others that have been tried", I believe, you know who said (or could google). So, if you will invent something really better, I will respect.

To be exact, GPL requirement "distribute code limitations should not exceed distribute binaries limitations", and it include derivatives, and this is tricky thing. For example, if I will use GPL licensed code in some my commercial

It depends on public opinion. In some countries people think, taxes must be equal for all, or linearly grow (and with ideally smooth function). They even sometimes change mind and make experiment with other function. Many experts think, thi
