After the last episode, it seems like the tech discrepancy between TOS and Discovery got just a bit wider. While before now the tech differences were mainly cosmetic instead of functional, it's now confirmed that Airiam is a cyborg rebuilt from an extremely damaged human body. Why couldn't TOS tech have done the same for Pike? At the least there should have been a vocabulator built for him to speak instead of that beeping wheelchair. The discrepancy seems jarring now.
