Wouldn't the training set (until end of 2021) be outdated?

What Apple has perfected over the year is energy efficiency.
The much better memory management hence lower RAM requirements for iOS, the stricter control on background processing, sensor management, processor design, reasonable resolution... all contribute to delivering more processing and usage for the same amount of energy.
What constraints Android phones is battery size and this is why we have seen ever increasing phone sizes without significant autonomy gains. Going small first requires a much leaner battery and this is the reason why Android phones have trailed the iPhone Mini IMHO.

Can someone explain how the 8 months old "withdrawal" is only seen now and required hacking the computer.
Isn't the point of the blockchain you can trace (except through mixers or specific ZKP systems) transactions precisely because every node holds an exact and full copy of the ledger of transactions?
The only thing hacking the computer could provide is private keys to actually transfer value out of those wallets but the balance should have been public.

There are many different areas of IP, not to be confused: patents, trademarks, industrial design, geographical indications, copyright... with different issues and problems.

IMHO there are areas of IP that make sense: protecting brands, otherwise known as trademarks, so that "company identity theft" is more difficult.

Patents were initially created not only to protect the inventors by giving them a limited monopoly time but also to
    1. encourage publication of inventions so secret inventions would not die with their owners, in effect creating a global corpus of invention descriptions.
    2. to help distribute the collective invention effort instead of having everyone try to replicate a given useful invention, in effect encouraging innovation. this is why patents are published before they are accepted.

The problem i see with the monopoly given is that too many patents are obvious and in effect lock-down effects stifle innovation instead of stimulating it. In a perfect world, the length of protection should be connected to a measure of obviousness and to the speed of the industry. It takes longer to apply an invention in the field of trains than in the field of software.

Sounds hard but a panel could grant patents a variable length, which would also help filter through the massive number of frivolous patents that chokes the patent offices.
