> Gödel’s second incompleteness theorem shows that you can prove anything, without that proof being meaningful is a lens into that.

What has Gödel incompleteness to do with that? We can just take any sentence φ as an axiom, and we’ve a trivial proof thereof.

Most people at e.g. Oxford and Cambridge (and, I suspect, many other universities) use their university emails for a fairly wide variety of extramural correspondence, and are stuck with M$ as the provider, alas.

> To get in, you need 4 A* from an independent schools

This is not, generally, true. Cambridge tends to have higher offers, and I had a friend offered 5A*+S1 (STEP), but that’s mostly because he buggered up his interview (and he was taking 5 A-levels). The standard offer at Oxford for mathematics is A*A*A, which is exactly what those applying from any public school will be asked to achieve.

> or just 3 As from state schools

Not for maths. For easy courses like PPE, someone who misses a standard offer of A*AA might be let off by a few grades. People at public schools who miss their offers are much likelier to be a bit thick.

What do you think fully homomorphic encryption is, then?

I don’t see how free software licences ‘sound too good to be true’, in that they don’t even sound relevantly good: they don’t suggest in the slightest that support will be available.

Gates is one of the best placed people to claim that the advantages of meeting people in person &c in disbursing his wealth (rather than just ‘giv[ing] talks’) outweigh the emissions. There’re obviously diminishing returns (do COP delegations need to be so large?) but it would be surprising if the optimum were zero flights.

The European Investment Bank provided €1.5b of funding.¹ EIB decisions don’t generally attract lots of attention from member states other than those concerned, since it is generally understood that the EIB is funding lots of projects in member states simultaneously. Similarly, the budget of the Commission and similar bodies will generally be set in advance, usually with a formal or informal understanding as to the broad distribution of funds between member states that will follow.

In any case, this project seems to me to be no more extraordinary than the redistributive effects of e.g. Medicaid or Pentagon spending, or the construction of Interstates. The Interstates, in the present US political environment, might indeed seem extraordinary; but the question is then not how one convinces people from state A to spend on state B, but how to convince people to make large long-term investments in the first place.

It’s rather odd that the ICO is saying this rather than industry lobbyists. No 10 is full of middle-aged technically unsophisticated types who want to look otherwise, and substitute credulity for wordliness, and I think Quangoland’s denizens are following the party line. (The shadow cabinet, but they aren’t that focused on growth because they have the luxury of not having to run the country.) The ensuing disasters may well be far worse than Horizon, if HMG ever gets anywhere with its AI plans.

Most important legislation, including the BNA, is government legislation (indeed, see the white paper: https://www.uniset.ca/naty/maternity/wpaper.pdf). It is therefore drafted by parliamentary counsel, whose advice remains available when amendments are proposed. Most governments also command sufficient majorities to push this kind of legislation through, or at least to come to consensus on amendments. The relevant passage seems clear enough that parliamentary counsel could have drafted it and so I doubt there were ‘too many chefs’ as you put it (although I haven’t checked Hansard).

It is also hard to see what these drafting habits have to do with the common law system. Points 1–5 could be true of a legislature in pretty much any legal tradition.

The Turing machine has a tape of unbounded size so can’t be built simpliciter.

Moreover although it turns out that that model of computation is very robust and sufficient for all purposes in physics (unless black holes or something allow hypercomputation) Turing does not really definitively show that and in a way that can’t be definitively shown. All we have is a lack of counterexamples (admittedly a very convincing one.)

I don’t see why this intuition is that helpful generally either; Turing machines don't really help at an implementation level with modern engineering problems as far as I can tell. Most of the time you know that what you want to do is possible in finite time &c.—presumably the difficulty is doing what you want to do, and going via the Turing formalism would be a bit odd.
