As someone who works in this field, let me add some thoughts:
Marvel is a joke. I put it at less than 10% that they would even beat the NIF record by 2035.
ITER is planned to turn on by 2025, but by now that is late 2025 ("turn on" means "create a plasma that is no more interesting than that in a fluorescent lamp"). From inside channels I know they plan to announce further delays later this year. Even if everything goes according to the present schedule, actual deuterium-tritium operation is planned to start in 2035. They will ramp thing up carefully, there
"Ehrlich" is German for "honest".
Nominative determinism strikes again?
