B&W is for purists imo, but there will always be purists, today, tomorrow or in 100 years.
I asked my 20 year old nanny and 2 of her friends if they had ever seen a B&W movie and they laughed at the idea. It makes sense to me. I was exposed to it as a child and saw a fair amount of B&W movies, but if you haven't, why should you care? I haven't seen one in years, and I don't know if I will ever expose my kids to B&W. I won't teach them how to use a rotary phone either, or warm their bath water on a fire. They will, instead, teach me about the future and I will try to learn. History is important, museums are important, but I don't think 30 years of B&W movies matter that much. It's all personal, though.
