Paul Graham Says YC Now Funds Nuclear and Biotech Startups

Paul Graham wrote that the startups Y Combinator funds now are much more serious than they were in the supposedly good old days. In the last couple of days he met with startups making optical switches, rewriting the software infrastructure of manufacturing, making nuclear reactors, and curing cancer. Blake Scholl replied to the post by stating that the YC for startups building a better future is YC. The two public posts describe current activity at the accelerator without naming any specific companies.
