Why the future of Artificial Intelligence & computers may be analog

I am not denying the analog computers, they may be back in some people atention, but I don't exactly want owning such computer and there are few reasons for this.

• Each analog computer is build with a specific reason in mind accondly to current technology (that may change but for the monent their circuits are very specific). That makes them consuming less energy comsuming and that may make them fast or even faster than some modern day computers but they can't be programmed. For example, you may have an analog computer that's showing you the clock or that's estimating you the meteo conditions for the nexr day but you can't access websites like this or platforms like Facebook, Twitter or Youtube with that computer. You will need or you will probably need if the technology changes different computer for each task you are doing. With modern day computers you can read this text and watch the video shown by Matt Ferrell in the same time on the same device no matter if it's a PC, laptop or smartphone.
• I am a software enginner and a science fiction writer. Using an analog computer means losing my activity and that would make me a full time kenshi (a person who's practicing kendo). I love practicing kendo but I don't exactly want doing it full time (I also love to program devices like the one you are using right now to read this and I also love writing science fiction stories).
• The analog computer are big because they need bigger and I am using laptops and smatphones for my websites and my applications. Where do I put the analog computer while moving from my place and customer place or moving around the city on the bicycle. Should I put it in my Time Lords pockets that are bigger on inside?
