While processing speeds are certainly linked to Moore's law, it is really only about the bi-yearly doubling of the transistor count while keeping prices roughly the same. Increasing the amount of cores and adding more on-die memory are easy ways to keep Moore's law going.

...well, easier than decreasing the half-pitch below 12nm.

By the way, Moore's law applies to memory density and CCD properties as well, neither of which appear to be close to their limits.

Unlikely...

The titles you see appearing in places like GOG and Steam are almost all well-known big titles by companies that still exist. This is only a very small part of what most abandonware websites offer. There's a huge number of great games that never gained any real following due to various reasons, or are owned by companies which no longer exist now.

In short, the real meaning of "abandonware" is exactly what its name implies: software which can be considered abandoned, preferably because there is no (clear) copyright holder anymore.

Then again, I can probably be considered biased, since I am webmaster of an abandonware site myself :)

What about 'rm -- -helloworld' ?
