No language other than C and FORTRAN have correct numerical libraries with a decent amount of speed.<p>Would you like the next plane that will make you travel to have the math done in javascript?<p>Would you like your pacemaker to fry 17W&#x2F;h for a V8 engine and do you need mozilla embedded in it ?<p>Would you feel safe with nuclear plants control on the cloud?<p>Does a space probe rather needs support for an oauth2.0 or correct numerical analysis?<p>Don&#x27;t you care that banking systems are correctly translating numerical amounts?<p>I mean computer are used for critical purpose too.<p>EDIT PS: numpy in python is binding on fortran libraries to do the job.
