I rest my case...
'Infinite'
You keep using that word. I do not think it means what you think it means.
There are a limited number of ways of arranging the atoms to make an antibiotic. That means there are a finite number of antibiotics.
I teach Chemistry at one of the top 10 Universities in the country. I have done research for 15 years of my life, so I don't need a lesson on how atoms arrange, please. This is not the point
The point is economics... the reason why hardly any antibiotic has been "discovered" over the past 10-20 years is simply because ot enough resources have been put into it... the pharmaceutical companies need a return for their huge investment and a new antibiotic to be used sparingly in those MRSA cases where nothing else works is not an incentive.
There are two ways to break the deadlock
1) The government pays for research and development
2) the government offers even more tax breaks for research and development
If you are not prepared to accept that drug discovery is simply down to money and instead believe that all the antibiotics have been discovered already, then fine, it is your prerogative, but I have no desire to discuss with anyone who has these medieval beliefs. We are simply too far apart to even talk
Hence my "I rest my case"
