Indeed, you can find out by yourself. Go get a helium-filled toy balloon
and leave it in a stable temperature room. Within days, it will shrink and
wither, thanks to the helium going through the latex balloon membrane. Also,
remember those "serious" deep diver watches, with an helium vent to get rid
of the helium that seeps though the glass while the "serious" deep diver is
slowly being decompressed...

have been able to send men to the moon without using
either microprocessors nor the metric system.
