The US college system is under a lot of stress right now. Also, just about everything about this thread is wrong
College debt is a huge problem. States have been underfunding public universities for the last 40 years. This is one of the main costs of exploding student debt. The states should honor their commitments to educating their populations. Boomers were the last generation to benefit
The federal government could step in an subsidize public universities if the political will were there. Cancelling student debt is a band-aid over the grave injustice of the last 40 years. It can and should be accompanied by free public college. This is doable.
Anyway, public universities still relatively cost effective means of training the tech sector. If the tech industry values this service it should support universities more (and not just the top 5) or push state and federal government to support this public investment in labor
Learning technical skills without a college education is fine. But let’s remember that this usually happens when people have high levels of privilege. There is a vast pool of creativity basically locked out of the tech sector right now.
How many future <fill in your favorite tech personality>s haven’t happened because of lack of equity? (But go on congratulating yourself for your privilege.)
Universities were never places of hyper focused learning (at least not the modern university). They operate as social network building institutions, and also relatively safe places to learn to become adults.
What’s wrong with stating one’s privileges up front? What are you afraid of? That the truth will make you look weak? Man up.

I’m white, male, and my father was a professor. I had mentors that helped me, plus a couple of really lucky breaks. Hey, my self-worth didn’t crumble.

What’s wrong with “explainable A.I.”

(Making the rounds again.)

1. Most XAI algorithms were not designed with humans in mind or consideration of what doctors really need help with

2. I still believe in the power of XAI, but research is still nascent ...
fortune.com/2022/03/22/ai-…
3. Verification, which is advocated, serves a different purpose than explanation. Verification tells us whether a system is compliant with regulations. Explanation can tell us on an instance-by-instance timescale whether to trust the system.

4. It’s not one-or-the-other, do both
5. But first, we need to be farther along with human-centered XAI so we don’t develop the wrong thing. Or worse, deploy a system that accidentally engenders inappropriate trust.

6. We would never want to prematurely deploy AI, right? … Right?

Rich white dudes will go to great lengths to avoid their money helping marginalized communities Image
Tell me how this doesn’t just end up giving money to those who already have privileges? What does this individual look like? Someone who doesn’t have food and housing insecurity so they can focus on their studies in K-12 and find themselves with time and energy to do more.
Anyway, this is basically what university looks like for affluent families. 4 years undergrad gives a lot of extracurricular time if one doesn’t have to work a side job. 5 year PhD; usually free for students in STEM.

I’ve been told my conversations with the author were influential to this book and that it says nice things about my research
“There’s no manual of human interaction, Riedl sighs”
The topic is a system Brent Harrison and I worked on in 2016, called “Quixote”

Here is one of the papers:

I would normally never send anyone to Lesswrong. com, but someone posted about Sam Altman remarks about OpenAI’s plans for GPT-4, and I have thoughts lesswrong.com/posts/aihztgJr… 1/7
GPT-4 will focus on coding (ala Codex). It will not be much bigger than GPT-3. The focus will instead be "line of sight" planning. Which is not really planning, it just means bigger context windows and output windows. 2/7
A long enough output window looks like lookahead, but is still just applying historical patterns to new problems. Dare I say "case based reasoning"? 3/7

I used GPT-J to create new loot items Image
Sometimes GPT gets a bit over-excited and starts to tell a story instead Image
It took longer to download and launch GPT than it took me to engineer an prompt that worked colab.research.google.com/drive/1Y392okU…

In about 3 weeks universities will be in session again. Many universities (like my own) want to pretend that things will be back to normal. The buildings and classrooms and quads will all be there and look the same. The routines of commuting to classes will be the same… 1/7
But WE will not be the same. We may still be suffering from mental fatigue. We may have developed new life routines and work habits that are suddenly incompatible with on-campus life. 2/7
2nd year students will be expected to act like 2nd year students even though they are navigating the new social norms of being away from home for the first time—something students normally learn in their first years. 3/7
