Despite being discriminated against and often being legally barred from opportunities, women still managed to invent a huge number of things that we use every day. These include but are hardly limited to:
The electric refridgerator was invented in 1914 by Florence Parpart.
The dishwasher was invented by Josephine Cochran in 1872.
Central heating gas furnace was invented by Alice Parker in 1919.
The electric water heater was invented in 1917 by Ida Forbes.
Cardiovascular drugs and anticoagulents were developed by Ruth Wexler who has over 190 medical patents in her name.
Immunosuppressive drugs were created by Gertrude Belle Elion in 1957. She also developed drugs for treating herpes, malaria, AIDS, and cancer and won a Nobel Prize in 1988.
Laser cataract surgery was developed in 1981 by Patricia Bath.
Bullet proof fibre (Kevlar) was invented in 1966 by Stephanie Kwolek.
The car heater was developed in 1893 by Margaret A. Wilcox who figured out how to channel air over the engine and into the vehicle.
The first computer algorithm was invented by Ada Lovelace, 1843.
Wireless transmission technology was invented by movie star Hedy Lamar in 1941. She’s why we have Bluetooth, GPS, and WiFi.
VoIP (Voice Over Internet Protocol) was invented by Marian Croak in 1982
The first solar powered house was invented by Maria Telkes in 1947
Software that made the 1969 moon landing possible was created by computer scientist Margaret Hamilton.
Rosalind Franklin discovered the double-helix structure of DNA only to have two men take credit and win the Nobel Prize for her work.
Lise Meitner discovered nuclear fission, only to have Otto Hahn remove her name from the paper and win the 1944 prize in chemistry from the Royal Swedish Academy of Sciences.

This list barely scratches the surface of all the things that women have invented and discovered. But why do you even care whether women think they need you are not? That's somebody's personal expression - one that is hardly universally held, mostly because it's so meaningless. Of course, if half the population suddenly disappeared or stopped doing their jobs, it would effect the economy as a whole, but it's not exactly like we'd still be living in caves if men had never existed.
In fact, the real question is, how many more things could have been invented earlier if women hadn't been so held back from doing so? The follow up question is why are so many men in STEM (and the world at large) still threatened by women to the point where they commonly harass women out of technical fields? If you really want to be "a little bit smarter and more thoughtful" perhaps you should be turning your attention there.
