By next year, I will be working here for ten years.

Untuk menunjukkan durasi hingga suatu titik di masa depan, gunakan will have been + V-ing, bukan will be + V-ing

By the time she retires, she will have been knowing him for 40 years.

By the time she retires, she will have known him for 40 years.

Verba statif seperti know, own, dan believe tidak dipakai dalam bentuk continuous. Gunakan future perfect (will have + V3) sebagai gantinya

By the time we will get there, they will have been playing for an hour.

By the time we get there, they will have been playing for an hour.

Setelah "by the time", gunakan present simple, bukan "will"

Tips

Tanyakan "sudah berapa lama, pada saat itu?". Jika jawabannya adalah durasi yang membentang hingga suatu saat di masa depan (for two hours by 6 PM), gunakan will have been + V-ing. Jika kamu hanya peduli bahwa sesuatu sudah selesai pada saat itu, gunakan future perfect (will have + V3).
