Panasonic introduced the G1 in 2008, following years of development. The future was clear then.

Not at all. I recall all kinds of issues with this camera, particularly it's beyond lethargic focusing. No one was proclaiming the future is mirrorless back then.

Its focusing was not "beyond lethargic" (though the first offering from Olympus was widely criticised on that basis). DP Review declared in its review.

"And our initial tests would suggest that they have solved at least one of the technological problems mentioned earlier (the contrast-detect autofocus is easily as fast as any other entry-level DSLR)." (emphasis added)

Phase detect has been fast for a long time. Contrast detect is still much slower. Did DP mean that the G1's AF was as fast as the live- view AF on a DSLR? I had a circa 2008 entry level DSLR and its AF was hardly as slow as even a current mirrorless.

You can read the article yourself. The answer is no, it was much faster than live-view AF on a DSLR.

The important point to note is that in the early days attention was focused on the ability of the cameras to focus on static subjects. DSLR live view was pretty hopeless at that, and the Panasonic cameras impressed by being much faster (one of the reasons was that the lenses were deliberately designed with light focusing elements, which could be rapidly moved back and forth as contrast detect requires).

It was only later that the emphasis shifted to the tracking of moving objects, where contrast detect had a big disadvantage relative to phase detect.

Of course, current mirrorless cameras are increasingly using sensor-based phase detect. This still has a way to go, but holds out the promise of becoming as good as the phase detect offered by DSLRs.
