The SLR was a great idea when needed to have a seperate path for

separate path via flip up mirror ?

It depends.

First, to drive two digital outputs (display + data recording) requires
the product to have more power ... both computational power and literal
power

(battery).

....and so the MILCs which work do just that.

Second, an LCD display isn’t always a good thing to view through, as
there’s lag for example, which degrades tracking performance of moving
targets.
The classical optical path operates at 186,000 miles/second, which is a
few femtoseconds, whereas the digital display replacement requires
photon to
electron reception on the CCD, followed by a data read, then data
transmit, data processing, another transmit, & finally to be
redisplayed. Even with
current technology still takes bunches of milliseconds...and try to
see where this metric even listed in product reviews: it’s already
been found that in 3D
VR simulators this delay often causes nausea in human subject research
volunteers (and thus, limits/affects experimental designs).

What are you trying to say? We are not discussing 3D VR simulators.
Have you tried one of the latest MILCs such as the X-T2, X-H1, or the
Sony a7III? ...and then there are the latest releases such as the X-T3
where there is no blackout even at 30fps.

Similarly, in pragmatic field use, one classical photography principle
is to put the sun at your back ... but this means that the sun is now
positioned so that it will illuminate your
LCD display & degrade its readability unless it’s shaded - such as
being designed with the same eyepiece cup as classical SLR’s. FYI,
shooting during Golden Hours results
in a much lower sun angle which can accentuate this as a problem...the
outcome is that the photographer needs to have a big fat head to make
shade to see what he’s framing.

You do understand that MILCs have an EVF which is used in much the same
way the traditional OVF is used on a DSLR. Try one some time you might
be surprised.
