Flashback: What May Happen in The Next 100 Years?

Old predictions are an interesting way to look into the dreams and fears of the generation making them. Here's a set of predictions from 1900:

"These prophecies will seem strange, almost impossible. Yet they have come from the most learned and conservative minds in America:

• Ready-cooked meals will be bought from establishments similar to our bakeries today.
• Automobiles will be cheaper than horses are to-day.
• Wireless telephone and telegraph circuits will span the world.
• Store purchases by Tube. Pneumatic tubes, instead of store wagons, will deliver packages and bundles.
• There will be no C, X or Q in our every-day alphabet.
• Grand opera will be telephoned. [...] Many devices will add to the emotional effect of music. "

I can see how wireless telephone could be seen as science fiction, but why ready-cooked meals?
