Infinite loop behavior in Go lang

The following code outputs zeroes in the console var i uint = 0 func show() { for { fmt.Println(i) time.Sleep(500 * time.Millisecond) } } func main() { go show() for { i++ } } output: 0 0 0 0 ... Only if I change the condition in 'for' to something like "for range 1

The following code outputs zeroes in the console

var i uint = 0

func show() {
    for {
        fmt.Println(i)
        time.Sleep(500 * time.Millisecond)
    }
}

func main() {
    go show()
    for {
        i++
    }
}

output: 0 0 0 0 ...

Only if I change the condition in 'for' to something like "for range 1<<32 - 1" it will output increasing values, e.g.: 4940 277284440 558609614 838787066 ....

Could someone please tell why it doesn't work the same way using an infinite loop?
