You have people procuring it.

There can be problems with them.

They may need replacement.

They are part of the manufacturing process.

They can hold back the line in production.

You need to source them.

You need to maintain them.

You have to have teams that write the firmware, all of it.

And then you also have to incorporate and fuse them into the system in some way.

And so it actually bloats a lot of it.

And I think Elon is really good at simplify, simplify.

Best part is no part.

And he always tries to throw away things that are not essential because he understands the entropy in organizations and in approach.

And I think in this case...

The cost is high, and you're not potentially seeing it if you're just a computer vision engineer, and I'm just trying to improve my network, and is it more useful or less useful?

How useful is it?

And the thing is, once you consider the full cost of a sensor, it actually is potentially a liability, and you need to be really sure that it's giving you extremely useful information.

In this case, we looked at using it or not using it, and the delta was not massive, and so it's not useful.

And these sensors, you know, they can change over time.

For example, you can have one type of, say, radar.
