fills them with joy, lightens up their mood even a little bit by 0.001%.

Or is it something that is just basic?

And I think if we can...

bring some value in people's lives, even through these subtle details.

We have to definitely invest our time in it.

People like when other people care.

That's, again, an intersection of art and technology.

Because you look at the stickers which Telegram launched way before most of these other apps.

Ahead of WhatsApp, yes.

But the stickers that WhatsApp ended up launching three years and eight months after, the first version was not really good because they just did regular GIFs or WebM videos

which were not based on vector graphics.

What we did is vector animations.

Each of these stickers is only several kilobytes, sometimes maybe maximum 20-30 kilobytes in size, but it says 180 frames.

We were able to run them at 60 frames per second on all devices.

and it's also very challenging was a challenging thing to do we had so much headache trying to make it work nobody even tried to do anything like this before us because it's crazily difficult but as a result you have this fluid animations you have this really nice user experience somebody sends you a sticker you don't have to wait for it to load because it's so lightweight

And it starts moving instantly.

And then, of course, it's not just engineering.

You have to find designers that are able to create these stickers using vector graphics, which means they're based on curves described by formulas, not just created as photographs with pixels.

Where do you find these people?

Again, we need competitions.
