This would not be horribly hard to do without the deep fake stuff. 1000 names covers ~72% of the population. Change the video a bit so you have a cut just after the name (One that looks like it fits and you could record just the hello name part and have the other 90% be the same.

Then you send the 237 Mikes the same video but now it is not a deepfake. Once a week or month you sit down and record any new names for half an hour or so.

Longer time sure but not 10k videos long like he implies.
