 > Note: `spawn` will always spawn a *new* future. You most likely don't want to call it on every render.
 
-The future must be `'static` – so any values captured by the task cannot carry any references to `cx`, such as a `UseState`.
-
-However, since you'll typically need a way to update the value of a hook, you can use `to_owned` to create a clone of the hook handle. You can then use that clone in the async closure.
-
-To make this a bit less verbose, Dioxus exports the `to_owned!` macro which will create a binding as shown above, which can be quite helpful when dealing with many values.
-
-```rust
-{{#include ../../../examples/spawn.rs:to_owned_macro}}
-```
-
 Calling `spawn` will give you a `JoinHandle` which lets you cancel or pause the future.
