question regarding relative security of md5 vs sha1

Hash: SHA1

so let me get this straight, if moore's law is 'true' than a mathmetical 
analysis of hash sizes will result in it being ~30 years before md5 will 
be susceptible to bf/dict/b-day attacks, but it will be about about 80 
before sha1 will be susceptible to cracks of that level.  I know this is 
sort of OT but I couldn't think of anyone more qualified than the 
experts of the crypto software I am using.
