on legacy…

proposition: not all legacy is bad

so we will call bad legacy obsolescence

proposition: not all obsolescence is significant

and we will call significant obsolescence debt

when is obsolescence a real problem?

when it offends your aesthetical sense

when it offends your aesthetical sensewhen it fails to use latest and greatest tech

when it offends your aesthetical sensewhen it fails to use latest and greatest techwhen it keeps you from improving effectively

why do we care about legacy?

AGCO FTW, YO!

why is innovation important to us?
