I don’t know I think it’s probably pretty accurate because whatever the AI process used it does have a cost. I think you are discounting significantly what that cost actually is. AI maybe less expensive but it’s not free.
And besides let’s say it ends up being 50%, because of the way numbers work, if it is 50% it is also therefore 30%, and 25% and 1% and 42% and 9% and 47%. Anything less than 50% would also be correct.
