I'm a web developer, so... Not me, but there are people who manage important web portals, for healthcare and security stuff.

Cashier & Customer Service. Who are Karens gonna yell at without us?! Society would collapse immediatly.

How exact are we getting? I'm an "assistant term professor", but I'm not an associate or tenure-track position, nor am I an adjunct. So i imagine if just people in my middling position disappeared, we might be fine, a bunch of adjuncts get a raise and a stable job, universities might have to reduce admissions or pack their classes, but we'd probably be fine in the long run. If all college professors disappeared, though, society might collapse. Suddenly you have millions of college students with incomplete educations who need to go somewhere. The brain drain on the world would be immense, and with the death of university-led research, we'd probably enter a dystopian future where all new research is being done by corporations.

Graphic designer. AI is getting pretty crazy so you all could be just fine. AI will make you what you want but will it make you what you need? Just sayin.

Social Worker, so maybe some parts of society would come crashing down at first but maybe turn out for the better in the long run. More specifically, working in a hospital currently, helping set up support structures for after the patient is discharged. Maybe we'd end up with people staying in hospitals for longer or visiting more frequently, could be a big hit to our Healthcare system, could force some much needed changes.

I could best be described as an "emergency draftsman". And potential damage could be far reaching in scale.

I work for a company that, among other things, makes replacement parts for things like power plants, chemical plants, any large industrial installation. In many cases, the thing that breaks is a one of a kind part, or something last manufactured in the 1960's, or some other thing that you aren't going to be able to just go buy a replacement. So what happens is someone will occasionally drop a broken something or other on my desk, and I have to figure out what it used to look like, then make a 3d model and a drawing of the part so it can be reproduced.

Food service? Dead within days...

Alot of people with mental health issues would be wandering the streets. Some would simply die at home due to not being able to look after and feed themselves. A fair few would be going around sexually assaulting young girls/boys (not understanding they're adults & it's wrong) and alot would be so pissed off and confused they be trying to kick the shit out of anyone they'd see. The world wouldn't end but it'd be a pain in the arse to navigate.

within a few hours. water and wastewater don't treat themselves. water would stop coning out of taps. wastewater would back up into people's homes and without a way to deal with it the environment would go to shit.

damn this makes me feel like i might be doing something important. i should be paid more

I don't even want to imagine a world without associate editors.

the work will be done for people with slightly different job titles? there is a lot of different titles that are mostly the same

Wholesale food buyer. A lot of people die from starvation.

Admin paper pushers coordinate so others can have frictionless meetings. Most likely all meetings will be awful, and initiatives will not have approvals so fraud will propagate quickly

Software engineer. It's better this way /s

Embedded software designer, so a lot of stuff I worked on in my life might stop functioning for whatever reason, small stuff like Nest thermostat you can replace with mechanical ones, etc. Aerotech stuffs might be more problematic... but planes and helis were flying in the 50s without software

People would die as X-rays and medical devices stop working. The power and communication grids would go down. Everyone's financial and personal data would be compromised. No one can make any purchases, because credit carding systems stop working. Cash is no longer accepted because no one knows how to do the math to make change anymore. Humanity would be in a stone age in less than 3 days.

IT helps desk.

Risk Analyst. Literally nothing would change except quite a few people would be pretty happy they don't badgered to fill out incident memos

Senior software engineer. Lots of bugs and mistakes from juniors and associates. Good luck lol.

I'm the political advisor to a politician....

You don't want to know

Industrial project engineer. Consequences of losing those jobs? No more new production plants and maintenance forces would quickly get overwhelmed trying to handle upgrades on top of routine maintenance. Profits would plummet. Plants would shut down.

Suddenly games wouldn't see a localised version anymore. To play anything that requires language comprehension, you'd have to study the source language.

This thankfully doesn't impact me personally, but people would lose out on some cool content. Not everyone finds it fun to spend years to acquire a language to the degree some games require.

Maybe arcade would make a comeback.
