motherboard/chip which will be most upgradeable?

I’m don’t want to start a mother board or amd/intel fight, but I am interested in hearing the enthusiasts opinion on the chipset and motherboard that will be most prepared to deal with the future technologies that will be coming through the computer pipeline.

Future of tasking, future of gaming, future of VR, future of AI, and machine learning through home computing.

Right now I have an intel I9 10850k with a z490 mother board on order with an rtx 3090 mainly because I was looking a fast single task gaming rig.

What I’m wondering is if this z490 board will be around for another decade for future iterations? If I’m gonna pay that much for a chip and board, I want it to be able to handle whatever can be thrown at it for the next decade.

Will we start to see games utilize more cores in the future to squeeze more speed out of the chip?

Should those of us with computer with only 10 cores and 128GB ram be concerned that we’re really gonna need 32 or 64 cores on down the road?

Somebody might ask what are the plans for computer.
I don’t do a whole lot of rendering or video editing. I am interested in machine learning, AI, and python Potentially writing complex algorithms for retail market trading. And from gaming standpoint high end RTS, 4K and VR gaming.

I don’t really care about the first person shooter games like COD, etc...

No matter what board you buy now, in 5 years, 6 tops, you have reached what I have over the last 20 years of gaming with custom rigs, can't do much with them as far as upgrading without swapping out to a new MB and go from there. Hence, 4-6 years, maybe a new gpu in there somewhere, then I just spec another to be bluilt for me. Just my thoughts and experience with it all.

And Cretae does make a very valid point, always go for the latest tech on the mobo (usually means $$$$$) and right now that belongs to AMD - PCIe Gen 4.
