When maple syrup, molasses, maple/corn/rice/malt syrup, agave etc. and soy/rice/oat/almond/coconut milk are readily available and affordable now, it's easy to avoid honey and milk today if you want to for environmental and/or ethical reasons. I'm pessimistic that e.g. lab grown meat will have a big impact unless it tastes identical to beef while being cheaper - the above alternatives are available now for other food types but it's still not enough incentive for most people to change. Any difference in taste will be a huge downside (most won't give their tastebuds a little time to adapt to a new taste without a good reason) and there's always going to be unfounded claims about what's healthy and natural.
