SewerAI | Walnut Creek, CA | Fullstack Engineer, Pythonista | Full-time
SewerAI is applying AI to the massive problem of sewer overflows. Most people aren't aware but our sewer infrastructure is crumbing around us, leaking enough sewage nationwide to cover the entire SF bay area in 7" of raw sewage.
We are revolutionizing the antiquated industry by automating the labor intensive part of labelling cracks, roots and grease in pipeline inspection videos.
We are a funded early stage startup with our first customer looking for a scrappy developer to help build our infrastructure and AI system. We are python focused.
Come join a startup that is solving a real world problem with AI.
It already has: hip/knee replacements, surgeries to repair where human body couldn't do so well, antibiotics to supplement the immune system, immune-boosters to boost it, iodine added to salt, sunglasses, sunscreen... There are literally hundreds of ways science is adding to our evolution by improving our bodies' biochemistry.
I’ve heard Titanium (like used n joint replacements) is actually weaker than bones. It’s better than not having the surgery, but you are not Wolverine.
You can't really compare bone and titanium in terms of strength. Bone is strong in compression but weak in tension and extremely weak in shear. Titanium is slightly weaker in compression but dramatically stronger in tension and shear.
Bone works great until it fails catastrophically (ie it fractures, breaks, and shatters) while titanium will begin bending long before it breaks. The latter is generally preferred in engineering structures, but since a human can heal its bones, the sudden failure is an acceptable compromise for consistent performance even at high loads.
Finally, bone weakens as we age, as does the body's ability to heal itself. Eventually wear and tear will make joints highly uncomfortable and the potential damage from otherwise minor injuries significantly greater. Titanium holds up well in the body over human timespans, and our ability to replace titanium components far exceeds our ability to artificially regenerate bone.
There are good reasons why evolution favored a composite like bone for our structural elements, but if you could magically replace your skeleton with one made of titanium once you were past your prime, it would be an unambiguous upgrade.
Evolution is a game of risk and reward - there's no piece of biology that is optimal, it is all 100% "all things considered, good enough". We're in a place where we don't have to balance those same energy/material concerns on a biological scale anymore, and can introduce energy sources that don't place nice with biology.
Evolution is an iterative process and _every iteration_ has to be able to live and reproduce. It's limited by what it can do.
Like, just look at laryngeal nerve. It's pretty dumb that the nerve has to go around the collarbone. But it's not surprising when you think about the iterative nature of evolution. https://rationalwiki.org/wiki/Laryngeal_nerve
And let's not even talk about the size of human skulls and maternal death in child birth.
The app witch lets you command-tab to switch apps but it lets you choose any open window of any app. So if you have 4 separate terminals and 3 chrome windows and multiple word documents open you can scroll to the exact one that you like
This is pretty spot on. I was on the receiving end of this and it’s incredibly challenging mentally to work hard to give away 40% to someone that just split. The comment about not being able to raise money is accurate as well.
Sell your stake for a fair value and wish the new owner luck. You could keep a few percent of stock but not enough to deter potential investors.
