Sure, I don't doubt that. The current proportion, from a quick google search, is between 1%-10% in the western world. That's after A LOT of effort and before any serious pushback.
Now try doing it for 99% of the population. The world population. How long will that take? 100 years? 500? Don't forget that historically impoverished areas are on the rise economically, and they want, justifiably, what they didn't have an abundance of - meat (among other things).
Now imagine we get real artificial meat, that people can't tell apart, but is cheaper, better tasting and nicer to look at. How long till we get the percentage of people who don't eat "real" meat up to 90%? 20 years? Maybe less?
So it's up to you how many animals will have to be killed before we stop eating them.
