Why you should make useless things | Simone Giertz

Hello.

My name is Simone.

You know how people tell you if you get nervous when onstage,

picture people in the audience naked?

Like it's this thing that's supposed to make you feel better.

But I was thinking --

picturing all of you naked in 2018 feels kind of weird and wrong.

Like, we're working really hard on moving past stuff like that,

so we need a new method of dealing with

if you get nervous onstage.

And I realized that what I'd really like

is that I can look at you as much as you're looking at me --

just to even things out a little bit.

So if I had way more eyeballs,

then we'd all be really comfortable, right?

So in preparation for this talk, I made myself a shirt.

(Rattling)

(Laughter)

It's googly eyes.

It took me 14 hours

and 227 googly eyes to make this shirt.

And being able to look at you as much as you're looking at me

is actually only half of the reason I made this.

The other half is being able to do this.

(Googly eyes rattle)

(Laughter)

So I do a lot of things like this.

I see a problem and I invent some sort of solution to it.

For example, brushing your teeth.

Like, it's this thing we all have to do, it's kind of boring,

and nobody really likes it.

If there were any seven-year-olds in the audience,

they'd be like, "Yes!"

So what about if you had a machine that could do it for you?

(Laughter)

I call it ...

I call it "The Toothbrush Helmet."

(Laughter)

(Robot arm buzzing)

(Laughter)

(Applause)

So my toothbrush helmet is recommended by zero out of 10 dentists,

and it definitely did not revolutionize the world of dentistry,

but it did completely change my life.

Because I finished making this toothbrush helmet three years ago

and after I finished making it,

I went into my living room and I put up a camera,

and I filmed a seven-second clip of it working.

And by now,

this is a pretty standard modern-day fairy tale

of girl posting on the internet,

the internet takes the girl by storm,

thousands of men voyage into the comment sections

to ask for her hand in marriage --

(Laughter)

She ignores all of them, starts a YouTube channel

and keeps on building robots.

Since then, I've carved out this little niche for myself on the internet

as an inventor of useless machines,

because as we all know,

the easiest way to be at the top of your field

is to choose a very small field.

(Laughter)

(Applause)

So I run a YouTube channel about my machines,

and I've done things like cutting hair with drones --

(Drone buzzes)

(Laughter)

(Drone crashes)

(Laughter)

(Drone buzzes)

(Laughter)

(Applause)

To a machine that helps me wake up in the morning --

(Alarm)

(Laughter)

(Video) Simone: Ow!

To this machine that helps me chop vegetables.

(Knives chop)

I'm not an engineer.

I did not study engineering in school.

But I was a super ambitious student growing up.

In middle school and high school, I had straight A's,

and I graduated at the top of my year.

On the flip side of that,

I struggled with very severe performance anxiety.

Here's an email I sent to my brother around that time.

"You won't understand how difficult it is for me to tell you,

to confess this.

I'm so freaking embarrassed.

I don't want people to think that I'm stupid.

Now I'm starting to cry too.

Damn."

And no, I did not accidentally burn our parents' house down.

The thing I'm writing about in the email and the thing I'm so upset about

is that I got a B on a math test.

So something obviously happened between here and here.

(Laughter)

One of those things was puberty.

(Laughter)

Beautiful time indeed.

But moreover,

I got interested in building robots,

and I wanted to teach myself about hardware.

But building things with hardware, especially if you're teaching yourself,

is something that's really difficult to do.

It has a high likelihood of failure

and moreover,

it has a high likelihood of making you feel stupid.

And that was my biggest fear at the time.

So I came up with a setup that would guarantee success 100 percent of the time.

With my setup, it would be nearly impossible to fail.

And that was that instead of trying to succeed,

I was going to try to build things that would fail.

And even though I didn't realize it at the time,

building stupid things was actually quite smart,

because as I kept on learning about hardware,

for the first time in my life,

I did not have to deal with my performance anxiety.

And as soon as I removed all pressure and expectations from myself,

that pressure quickly got replaced by enthusiasm,

and it allowed me to just play.

So as an inventor,

I'm interested in things that people struggle with.

It can be small things or big things or medium-sized things

and something like giving a TED talk presents this whole new set of problems

that I can solve.

And identifying a problem is the first step in my process

of building a useless machine.

So before I came here,

I sat down and I thought of some of the potential problems I might have

in giving this talk.

Forgetting what to say.

That people won't laugh --

that's you.

Or even worse,

that you'll laugh at the wrong things --

that was an OK part to laugh at,

thank you.

(Laughter)

Or that when I get nervous, my hands start shaking

and I'm really self-conscious about it.

Or that my fly has been open this entire time

and all of you noticed but I didn't,

but it's closed so we're all good on that one.

But one thing I'm actually really nervous about is my hands shaking.

I remember when I was a kid,

giving presentations in school,

I would have my notes on a piece of paper,

and I would put a notebook behind the paper

so that people wouldn't be able to see the paper quivering.

And I give a lot of talks.

I know that about half of you in the audience are probably like,

"Building useless machines is really fun,

but how is this in any way or form a business?"

And giving talks is a part of it.

And the arrangers always put out a glass of water for you onstage

so you have something to drink if you get thirsty,

and I always so badly want to drink that water,

but I don't dare to pick the glass up

because then people might be able to see that my hands are shaking.

So what about a machine that hands you a glass of water?

Sold to the nervous girl in the googly-eye shirt.

Actually, I need to take this off because I have a thing --

(Googly eyes rattle)

Oh.

(Clanking)

(Laughter)

I still don't know what to call this,

but I think some sort of "head orbit device,"

because it rotates this platform around you

and you can put anything on it.

You can have a camera; you can get photos of your entire head.

Like it's really -- it's a very versatile machine.

(Laughter)

OK, and I have --

I mean, you can put some snacks on it, for example,

if you want to.

I have some popcorn here.

And you just put a little bit like that.

And then you want to --

there's some sacrifices for science --

just some popcorn falling on the floor.

Let's do the long way around.

(Robot buzzes)

(Laughter)

And then you have a little hand.

You need to adjust the height of it,

and you just do it by shrugging.

(Laughter)

(Applause)

It has a little hand.

(Hand thwacks)

(Laughter)

(Applause)

I just bumped my mic off,

but I think we're all good.

OK, also I need to chew this popcorn,

so if you guys could just clap your hands a little bit more --

(Applause)

OK, so it's like your own little personal solar system,

because I'm a millennial,

so I want everything to revolve around me.

(Laughter)

Back to the glass of water, that's what we're here for.

So, I promise -- I mean, it still has --

it doesn't have any water in it,

I'm sorry.

But I still need to work on this machine a little bit

because I still need to pick up the glass and put it on the platform,

but if your hands are shaking a little bit,

nobody's going to notice

because you're wearing a very mesmerizing piece of equipment.

So, we're all good.

OK.

(Robot buzzes)

(Singing)

Oh no, it got stuck.

Isn't it comforting that even robots sometimes get stage fright?

It just gets stuck a little bit.

It's very human of them.

Oh wait, let's go back a little bit,

and then --

(Glass falls)

(Laughter)

Isn't it a beautiful time to be alive?

(Laughter)

(Applause)

So as much as my machines can seem like simple engineering slapstick,

I realize that I stumbled on something bigger than that.

It's this expression of joy and humility that often gets lost in engineering,

and for me it was a way to learn about hardware

without having my performance anxiety get in the way.

I often get asked if I think I'm ever going to build something useful,

and maybe someday I will.

But the way I see it,

I already have

because I've built myself this job

and it's something that I could never have planned for,

or that I could --

(Applause)

It's something that I could never have planned for.

Instead it happened just because I was enthusiastic about what I was doing,

and I was sharing that enthusiasm with other people.

To me that's the true beauty of making useless things,

because it's this acknowledgment

that you don't always know what the best answer is.

And it turns off that voice in your head

that tells you that you know exactly how the world works.

And maybe a toothbrush helmet isn't the answer,

but at least you're asking the question.

Thank you.

(Applause)
