Not day to day, but I can send a vial of spit off to a company which will then tell me if I have any genes which increase risk for certain illnesses. I can then take preventative measure.
For an old timey medical thing, which is really what you should be comparing your medical knowledge stuff to, not electricity, what is a practical, day to day, benefit of antibiotics? (I would argue the curing your sickness is a special occasion benefit, even less day to day than preventative measures taken from the genome thing).
Your point on antibiotics is a fair retort to my argument- Though if I had to choose between knowing a human's full DNA sequence or posessing antibiotics, clearly the latter is by far the superior item.
