Screw nuclear fusion.
The world will run out of helium before its developed.
Salvation is at hand:
With supplies dwindling, researchers discover a massive helium field in Africa

All the electronics manufactures in asia can buy African blood helium and we can keep our own supply for welding, weapons development and inventing stuff that asia will eventually make cheaper than the US can.

Hydraulic fractured natural gas turns out does not contain much helium. The high concentrations of helium collect in very old gas formations only the oldest on earth. Hydraulic fracturing speeds up the process of forming a gas deposit by a few million years so the helium just hasn't had the time it takes to be created and collected.

Since I last posted I did get my helium bottle filled, came back with "balloon grade helium" in it. Not sure what that means. Could be helium with CO2 or air to "water it down" or it could be 99% pure. If its got air in it then its pretty much useless for welding for me, if its got CO2 in it then I could use it for mig welding if I dilute the CO2 down to about 2% with argon. I could dilute the air down to about 2% and to do mig spray transfer but my 120 volt machine doesn't have enough power to do spray transfer.
I have built a 105 amp tig welder that works perfectly and I am about to complete a second much more powerful 230 amp tig welder. And I am starting to do aluminum. Tig tri mix (which is mostly helium) is great for tig welding aluminum.
