Not a stupid question at all. I’m not sure about piloted aircraft, but drones currently operate at altitudes where they can’t be seen or heard from the ground.
You are aware that old consoles still play games, right? My PS4 still plays all my PS4 games and lets me stream PS5 games to from my living room to my bedroom. My Xbox 360 still plays games just fine last time I checked (last June or so). Getting rid of old consoles doesn’t make sense unless you absolutely have to have the latest tech and also don’t have much storage space.
If we’re talking about aircraft, the combination of modern radar mitigation and modern sensor packages would allow a time traveling plane or drone to be effectively invisible in 1925.
Sure they’re not going to bend light around themselves, but they can fly outside of visual range and 1925 radar technology won’t stand a chance of detecting them.
“In conclusion, the statement that cancer screenings do not save lives cannot be properly drawn from the Bretthauer's et al. meta-analysis because lifetime gains are likely underestimated and based on uncertain all-cause mortality estimates.
…
Lifetime gains estimated for the screened group from all-cause mortality reduction is a misleading measure and should be avoided because it implies a benefit for all persons in the screening group, including those not affected by the target cancer.”
“Although gaps persist between the full potential benefit and benefits considering adherence, existing cancer screening technologies have offered significant value to the US population. Technologies and policy interventions that can improve adherence and/or expand the number of cancer types tested will provide significantly more value and save significantly more patient lives.”
