welp from what i can tell, you would need a HUGE tv or sit really close to get maximum benefit from 8k, so close it would probably be uncomfortable... so i would think the resolution aspect is good for quite a while to come.
Software wise, you can always get a set top box if your tv can’t support new apps or streaming services..ect.
Oled is still expensive, so if you’re budget is only 800-1500, then oled to you, is the next big thing ;P
Personally i have a feeling that future of tv companies might be focusing on making cool things like
this, rethinking the whole concept of the traditional tv.
