Products[]
One known product of WG systems are genetically engineered robots - commonly known colloquially as Meatbots. Examples of these include Abel, Faith, Bob and Becks. No other products are mentioned in the series. Time machines are not included in this list, because although they were invented by Waldstein himself in 2044 - inspired by a paper by Edward Chan in 2029 - he campaigned against time travel after either watching or saving his wife from a car crash, or witnessing the Kosong-ni holocaust after his first journey into the past, 16 years back in time.
This would mean that W.G. Systems certainly has a lot more products, or Waldstein wouldn't have his billions. One of these could be the Babel-Buds, miniature wearable devices that automatically translate sounds into a set language.
