    4/ One option would be to, you know, find a way to pay them. Turns out, giving people money is a good way to get them to do hard, highly technical work. Somehow, though, this point is controversial. himself made this clear during that debate:

    I'd go further. I've never met a coin-operated super competent systems engineer. They want a challenge and to build something that matters, profit is secondary (cause they rarely have issues getting a well-paying job when they need it).

    Bitcoin Core developers have known for years about the kind of high-assurance, formally verified code that bitcoin deserves. One of the problems is that it's profoundly expensive to go and make Coq proofs of everything.

    will you guys be funding more/better core devs, in light of this double-spend bug?

    Pushing updates by an aleet system is centralization and an even greater vulnerability. No thank you, Mr. Cobro.

    Bad move that the alert system was removed from Bitcoin Core. Currently 80%+ of the network is running vulnerable software, but there's no way to reach them and tell them to update, we can only pray they check Reddit, Twitter, or Bitcointalk, etc.

    A company without any bitcoin developers should never act as a bitcoin custodian. Sage advice, but as soon as institutional money is flowing, custodians will quickly outnumber devs IMO... though this will be an important differentiator.
