I'm really not sure what your concern is? They do this based on sematics with data which doesn't has the data. You can get more information out of pixelated data if you know what the semantics are. The search space is much much smaller if you only optimize for bloodcells than for everything. If this adds a chance of seeing things which you couldn't do before, it adds value. It could mean doing a cheap analysis with low res and doing a high res and much more expensive one when you detect something. Like being in a rural area and traveling to the big city after you found something. Overall the chances are that more people get help not less
