Bows and arrows have come a long way since the middle ages and they will continue to evolve in their effectiveness as time marches forward. So here are a few of the bows I think will be available in the future.
New Weapon Characteristics
Wireless (TL 11): Every arrow after the first successful strike on the same target made with the same bow with the wireless characteristic is granted a +1 DM as the arrow sends back positioning telemetry to the bow. This bonus lasts for 1 minute.
Wireless Bow (TL 11)
This short bow is made from an advanced polymer-metal composite. It features an onboard computer, allowing it to know the position of arrows it fired for a short time.
Weapon: wireless bow
TL: 11
Range: Rifle
Required Skill: Athletics (Bows)
Damage: 2d6+1
Recoil: 1

Wireless Power Bow (TL 13)
Functionally similar to older styles of bow, however, the addition of energy allows the bow string to recoil at ultrahigh speeds. So an arrow fired from this bow rips through light armor.

Required Skill: Athletics (Bows)

I don’t care if you had Tony add goodies to your bow, you still aren’t a superhero Hawkeye. :p
Still don’t get folks using a TL-2 weapon when every other weapon is so much better at TL-5+. So, cute, but still useless toy. Firearms with silencing tech or lasers can do the job better and at longer ranges. But then I like high tech. *shrugs*
