The R2 Unit We Deserve vs. The Cloud We’re Selling Our Souls Into

Ever since A New Hope dropped in 1977, and I saw how R2-D2 helped Luke & Han rescue Leia, I’ve wanted my own Droid. Not a marketing gimmick, not a surveillance drone—just a little friend to help organize my life. A pocket R2-D2. For decades, I chased every piece of tech that came out, hoping to find the magic. Digital notebooks, mini laptops, PDAs, iPads, iPhones, Verizon’s Official Star Wars themed Droid phone (yeah, I’m that nerdy). Nothing stuck.

A11y 101 – 3.3.7 Redundant Entry

You’re shopping online at your favorite store. You set up an account for future visits. You fill out your name, email, shipping address, billing info, card details. You save the info.

You start shopping and add some items to the cart. The checkout form asks for all that information again. Name, email, address, card. All of it. Fresh blanks.

You stare at the screen. “Didn’t you already know this?”

A11y 101 – 3.3.4 Error Prevention

Imagine buying a car. You sign a contract. Then you discover the dealership changed the interest rate after you clicked “Accept.” Or you transfer money to a bank account. You confirm the transaction. Then you realize you sent it to the wrong person—and the funds are gone.

These aren’t typos. These aren’t forgotten passwords. These are consequential actions with legal, financial, or irreversible data implications.

And if your interface doesn’t protect users from making these mistakes, you’re not just violating WCAG—you’re exposing yourself to liability.

That’s the core of WCAG 3.3.4: Error Prevention. Unlike 3.3.3, which is about helping users fix field-level validation errors, 3.3.4 is about preventing catastrophic mistakes before they happen.

A11y 101 – 3.3.3 Error Suggestion

You submit a form. An error flashes: “Invalid.” That’s it.

Invalid what? Invalid how? Invalid because you used the wrong format, or invalid because the email is already taken, or invalid because the server had a seizure and forgot what an email even is?

For all the user knows, the system is lying. The form is broken. They’re blocked, with nowhere to go.

That’s where WCAG 3.3.3: Error Suggestion comes in. And its message is simple: tell people how to fix it.

A11y 101 – 3.3.2 Labels or Instructions

Before I Can Fill It, I Need to Know What You’re Asking 

There’s a form I encountered recently that had twelve fields. No labels. Just placeholder text inside each input that disappeared the moment you started typing. If you forgot what a field was asking for, you had to delete everything you’d entered just to see the hint again.

Twelve fields. Zero labels. Infinite frustration.

That’s not a design choice. That’s a barrier. And it’s exactly the kind of thing WCAG 3.3.2: Labels or Instructions exists to dismantle.

Three Months Later: The Algorithm Won. My Wife Nearly Didn’t.

Trigger Warning & Note Before You Read

This post discusses eating disorders, mental health, adverse medication reactions, and hospitalization. If you’re struggling, please reach out to a healthcare professional. You deserve support.

Three months ago, I published “When Algorithms Forget You’re Human.” I wrote about my wife—recovering from an eating disorder, doing well (over a decade with no lapse), dealing with weight gain from disability changes—and how social media kept serving her GLP-1 ads. Skin removal surgery. Weight loss programs. Sono Bello showed up eleven times after she blocked them.

I wrote about how algorithms don’t respect choices. How Amazon Prime offers no way to mark content as problematic. How AI systems act as yes men. How platforms treat vulnerability as revenue opportunity.

Today is three months to the day since that post.

My wife is in a hospital bed.

What Counts as Experience?

Finding a job these days is a brutal thing. Artificial intelligence is doing the initial screening and the interviews. There are ghost postings that never lead anywhere. If you do get through, people are facing five, six, sometimes seven rounds of interviews, only to be left hanging, wondering whether there will ever be feedback. Recently I had several colleagues go through this entire process—screening, panels, take-homes, final rounds—only to be rejected and watch the company repost the same opening a week later.

I sat down with a couple of them to talk about their experiences. This is what they had to say. Names have been anonymized.

A11y 101 – 3.3.1 Error Identification

We’ve all been there. You fill out a form. You hit submit. Nothing happens. Maybe the border turns red. Maybe a little icon winks at you. Maybe your computer hums aggressively. But nobody tells you what went wrong.

You stare at the screen. “Did it fail? Did it work? Am I now married to a stranger?”

Silence is rude. Silence is inaccessible. And silence violates WCAG 3.3.1: Error Identification.

A11y 101 – 3.2.4 Consistent Identification

Why Labels Need to Match Across Pages 

You’re at a party. Someone introduces themselves as “Michael.” You shake his hand, have a nice conversation, move on. Later that evening, you see him again across the room. You walk over and say, “Hey, Michael!” He looks at you blankly. “It’s Mike now.” Weird, but okay. A while later, you spot him by the snack table. “Mike!” you try again. He turns around. “Actually, it’s Mikey.”

You’d stop trying, right? You’d start avoiding this person. Not because you don’t like them, but because the rules keep changing and you can’t keep up.That’s what inconsistent identification feels like on a website.

A11y 101 – 3.2.3 Consistent Navigation

Imagine walking into your favorite library. You know exactly where the fiction section is. It’s always on the second floor, to the left of the stairs. The librarian knows where you go. Your feet know the way. It’s muscle memory.

It is a week later when you walk in, and suddenly fiction is in the basement, behind the coffee shop, accessible only through a secret door behind the periodicals. The stairs are now an elevator, but it’s on the other side of the building. The librarian has vanished.

You’d feel disoriented. Frustrated. Maybe even a little unsafe. You’re just trying to find a book, not solve a puzzle.
