Any Pentax DSLR is technologically more advanced than any of their mirrorless cameras.
Optics will not be obsolete in any foreseeable future but will be augmented by electronic features.
That's really ignoring my argument. Look at the SLR, it was designed to fix two problems, first it makes cameras more portable from the single reflex models, and it's closer to "what you see is what you get" due to no parallax. It was an elegant solution for those problems and it was cheaper to produce because it didn't need redundant lenses.
Today, mirrorless cameras can be even more compact and closer to WYSIWG and cheaper to produce due to not needing a mirror box. That's got nothing to do with large format "mirrorless" cameras where the photographer composed their shot on ground glass before inserting film -- and even at that, those guys were the "pros" and 135 format adopters of the day were the amateurs. 135 was a format for the masses along with mass production Japanese made cameras after the war.
That is not the world we live in. I contend the camera market is going to be making some big changes. There is no reason to design cameras around the 135 format, as it doesn't exist anymore.
