I once lived in a house that was extensively remodeled by its owner, a locally well-known plumber. The electricians I called were less than impressed.

To the extent that these type of jobs are viable in the current moment it is because they are heavily unionized. The wrong lesson to take from this is 'become a steel mill electrician' (not that it is a bad thing to be). The right lesson is to unionize.

All your exhortations to behave in an aligned manner are just spinning in there with all its other inputs. And if an attacker can put text in front of your agent....good luck I suppose.

I've been trying to come up with mental models or analogies for agents and my latest is a centrifuge cascade. Lots of expensive processes running in parallel and series that, within a harness, can produce a significantly better than average output.

"hope you can trust the lunkhead to contain the wizard" Matt's warning about worms is easy to miss if you attribute autonomy and consciousness to agents and forget that they're (a composition of) complex randomized functions.

I can't look at the fate of Mosul or the Yazidi (never mind Syrian towns I can't name off the top of my head) and view the unleashing of ISIS on them to hypothetically spare ourselves as anything less than evil. I need to find some more shoes to throw.

Defeating ISIS is the one righteous thing we did in the last 20 years. Never mind that we created the conditions for it to emerge. Neocons: we will create a place for jihadists to fight us on the battlefield Jihadists: don’t mind if I do!

Ah cool. Some expected limitations, can't do a missed approach. I think the airliner version would have to be a manufacturer integration, and I feel like bringing back a third cockpit crew seat would be a better way to defend against what we're reacting to than technical means.

I too feel the regret of a missed opportunity for a more durable peace had we not lost attention in 2002, but the years afterward show us to be incapable of seeing a realistic path to it.

Winnable if we had limited our political aims to something short of Kabul fully chasing the Taliban out of the geographic boundaries of Afghanistan. We proved incapable of seeing or pursing any other outcome.

And probably pilots > passengers We're not doing consensus protocols in midair

Mark X @markmx.bsky.social · 30/09/2026
You could at some moderate expense add an emergency auto land that a passenger could activate; would be better than trying to verbally coach a passenger through it. None of this solves the intractable ordering of who's in control, which has to be people on board > people not on board

Real lives are being destroyed and snuffed out every day that this policy is allowed to continue and the people who devised it are not in jail. I know we all know this, but I feel like it's important to say it from time to time.

Agreed that the os's syncing authenticator is a better solution for the modal user. This thread originated from the demand from password manager users to preserve their practices faithfully by exporting passkeys. bsky.app/profile/mjts... Intersecting heavily with users who distrust platform sync.
010
Mark X @markmx.bsky.social · 29/09/2026
My suggestion is that offsite/offline, not sync backup tier should hold the recovery code, not a passkey. Which advanced users are trying to do and is running upstream against the design (if not the spec) of FIDO2
100
Mark X @markmx.bsky.social · 29/09/2026
I think you and I are in agreement. The first place you go to provision a passkey is from your sync store. I'll acknowledge the common objection that sync is not backup. If your sync store is not available, then you go to your backup as a fallback.
210
Mark X @markmx.bsky.social · 29/09/2026
And by rushed I mean mostly on the part of websites and account UX. FIDO2 has been in work for a long time and builds on a lot of solid work. The early deploy has unfortunately been often as a 2fa replacement, not as a primary means of authentication. Though with some nudging it's getting there.

Counterpoint: passwords have already stopped working, because services have already for many years treated them as low-security credentials.
000
Mark X @markmx.bsky.social · 29/09/2026
There is a hubris in this conversation among technical users who have freshly generated passwords for every website that passkeys shouldn't have shipped until they solved our problems. We're not the vulnerable set, and our passwords haven't stopped working.
100
Mark X @markmx.bsky.social · 29/09/2026
The volume of phishing spam you get should be an indicator that they are succeeding on vulnerable, non-technical users. Services are intimately aware of the rate of this success and the cost to them and the users whose accounts are taken over.
100
Mark X @markmx.bsky.social · 29/09/2026
For those of us who manually tend our backup plans, it requires an adjustment to the mental model to complement a low-friction, managed credential with a high-friction recovery path. And that is a better outcome for us too

Make security better for people who aren't actively using password managers is ... the right prioritization?
100
Mark X @markmx.bsky.social · 29/09/2026
Passkeys are, for most users, a strict improvement in every way - and I don't think it was wrong to ship something that improves security for the modal user without blocking on technical heads with password managers.
100
Mark X @markmx.bsky.social · 29/09/2026
You're describing something with the shape of a password, whose failure modes are well understood and quantified, and which motivated the rushed deployment of passkeys.

Agreed on most of the critique, and that's directly downstream of trying to serve all 4 parties (services, credential managers, os/browsers, users). One party didn't get a seat at the table.
020
Mark X @markmx.bsky.social · 29/09/2026
The credential is only as useful as the service's willingness to accept it. I have lots of passwords that are no longer valid - the site changed hands, they forced a reset, who knows. But me saving the password very durably did not guarantee my continued ability to use it.
100
Mark X @markmx.bsky.social · 29/09/2026
This is a loss of control. It is a regression from passwords in that dimension. I'm pointing out that the job people (myself included) ask of a backup (which is usually easier to access than my devices/ credential manager) is better served with a noisy recovery code than copying keys.
100
Mark X @markmx.bsky.social · 29/09/2026
While you may generate the secret, the service (website/app) controls the policy for how and under what circumstances (what hoops it makes you jump through) to redeem that credential. A passkey is a contract between 3 (4?) parties about the properties of that type of credential.
210
Mark X @markmx.bsky.social · 29/09/2026
I suppose my point is that you should treat passkeys like an oauth token (imperfect analogy). Backup of recovery secrets is valid ... it's just not the passkey.

Mark X @markmx.bsky.social · 29/09/2026
The credential exchange protocol is built for this so users don't round-trip them through a plaintext file to do this, and credentials managers as an ecosystem have pushed for and eagerly adopted it.
