No chance on running lots of other programs in the background... even a few tabs open in firefox and youtube running for music in BG, pretty soon show what such big RAW-files do to the speed of your workstation...
I'm going a little off-topic here, but thought this worth digging into just a little...
All my raw development and post-processing work is done on my 2013 HP ENVY 17" laptop with i7-4700MQ processor (4 cores @ 2.4GHz / 8 threads), 16GB RAM and GeForce 940M graphics. For a laptop, it's a pretty quick machine - still decent by today's standards. Previously, I used Windows 10 as my OS, with Lightroom 6 (stand-alone) for raw development and the Google Nik suite for additional processing, with occasional further editing with PhotoShop Elements. Some months ago I finally made the switch (after much side-by-side testing) to Linux Mint 18.3 and Cinnamon desktop, with digiKam, Darktable and GIMP, plus a few plug-ins for the latter. I usually have Firefox browser plus uBlock Origin and HTTPS Everywhere open with between four and eight active tabs, sometimes more... I often have BBC Radio 4 playing (via BBC's iPlayer streaming) while I work. On my old Windows setup, I also had Avast Antivirus running constantly.
I don't own a K-1 or K-1II... the highest resolution cameras I own are my K-3, K-3II, Hasselblad HV and Sony A7 MkII. All have 24MP sensors. But I've processed lots of K-1 and K-1II files to learn about the image quality and test how they respond to noise reduction, shadow and highlight recovery, and other aspects. On my laptop, both using my old Windows / Lightroom or my current (and faster) Linux Mint / digiKam / Darktable setups, I've had no problems whatsoever with system performance when working with the 36MP files. Exports to full size TIFF and JPEG take a little longer than I'm used to, but still quite acceptable. I'm wondering how much difference 42MP files would make?
That aside, I agree with you that 36MP is - for
most people - enough. I understand why some people want or need more, and I respect that. But I doubt the majority actually
need it. For me personally, 24MP is a great compromise. I get all the detail I need from the 24MP sensors on my full frame Hasselblad HV and Sony A7 MkII, and more than I need from my K-3 and K-3II, with reasonable file sizes. In fact, my most used camera is my 10MP Samsung GX-10 (K10D clone), which gives me roughly the same pixel density as my HV or A7 MkII but in APS-C format. For me, that's enough. But I'm not "everyone", so I can't judge what others might need
