As far as I know the current adpters for Sony and Fuji do not allow auto focus and reviews say they are not very good quality.

It's not that mirrorless fits my style it's more that their advantages seem very clear. Opinions may vary, but I think that's undeniable it won't take too long until high end mirrorless cameras take over the DSLR market. A bit like Tesla cars, new application of technology, already superior in many ways vs gas powered cars that have been around for much longer.
I didn't blame Pentax - However, for whatever reason they seem to be lagging behind in sales, popularity and third party support.
The advantages of mirrorless are over stated. The cameras are smaller -- as long as you don't mount a lens or only use a slow zoom. Stick a 70-200 f2.8 or 85 mm f1.4 and the advantage vanishes. EVFs have some interesting features -- focus peaking, histograms and can be brighter in dark situations than OVFs -- albeit for a price -- graininess, lag with most of them, and less battery life. As far as overall performance, you get what you pay for. If you pay the same amount for your mirrorless and SLR, you will actually get really similar performance. I am biased and think that the K-1 out punches the A7r, but certainly both have pluses and minuses.
What you are not going to get is A9 or D5 performance from an 1800 dollar camera, be it mirrorless or SLR.
My personal opinion is that mirrorless camera sales will slow as that market matures. This is the issue that SLR companies have faced for several years.
If you own an A7 then there is plenty of reason to upgrade, as your auto focus is pretty poor and overall camera quality isn't great. But if you own an A7r II, what is going to induce you to fork out another 2 or 3K on a new camera? 8K video? The ability to play Frogger on the rear LCD screen?
We will see what the future holds, but my guess is that there will be some balance between SLRs and mirrorless cameras in the future. Both will sell decently, but not like in the glory days of four or five years ago when digital camera sales were off the charts. Those days are gone and will not return -- primarily because people are holding onto their current gear longer.
As far as the whole adapter question, it is clear that the reduce the functionality of the camera (slow auto focus rate and frame rates) while adding to bulk. While they are a "fix" that allows for a transition to a new mount, they are not ideal and tend to drive current users to seek other options.
