And also an insightful YouTube comment(!) someone made in response describing their interpretation:

"This is one of the most thoughtful and insightful reviews on deeper film meanings I think I’ve ever seen. In keeping with the rebirth symbolism, I would offer the following possibilities.
The transport pod symbolizes more of a womb, rather than a gas chamber.
The chair may not be an electric chair but rather a means for Ellie to assume a modified fetal position while in the capsule. This would mimic the position of a baby of in a womb prior to its own birth.
The wires plugged into Ellie represent an umbilical cord to sustain her, rather than a means to kill her.
The periodic updates given by the mission control staff as to the status of the machine (10%, 20%, 30%, etc.) mirror the increasing dilation of women in labor (1 cm dilated, 2cm dilated, 3cm dilated, etc.).
The wormhole sequence mirrors the new life traveling through a birth canal.
The capsule takes on a liquid form to symbolizes the protective amniotic fluid to keep the new life safe.
After Ellie’s “birth”, the first person she sees is her father.
This rebirth scene is enhanced by considering Ellie’s mother died from complications of childbirth when Ellie was born. This backstory enhances Ellie’s natural reluctance to be reborn as her initial birth killed her mother, and permanently altered her life.
There’s undeniably imagery of execution and rebirth simultaneously occurring within the same frames! The filmmakers did an outstanding of capturing some very compelling storytelling while inserting remarkable symbolism."
There’s a video by a designer talking about some of the symbolism of Ellie’s journey (Full talk video here – SPOILERS for the film in both).
