- Comment on Interesting to see how dead the MMO genre has become. Are there still players around? 2 months ago:
Touche, forgot this was PatientGamers. Grim Dawn is basically the same sans MMO. It’s the best ARPG I’ve played like, ever, and it’s due for a huge DLC soon. Goes on sale for very cheap often.
Unlike Last Epoch, it’s more item-focused. Unlike PoE, the items aren’t a total nightmare to optimize…

Very interesting - I haven’t hit a single bug during my play.

A handful if my PoE friends have picked up Last Epoch which I’ve found to be more approachable. Little less MMO but a very similar game.

Nah. Fenced epee for a bit in a college club. Height advantage was pretty great. I guess it just depends on the weapon.
- Comment on Outer wilds: at what point should I give up? 3 months ago:
Outer Wilds was the best game I played on PS4. I strongly recommend experiencing it for yourself.
I would say the space ship/0g flight is maybe 30% of the gameplay, and you don’t need to be really excellent at it, thankfully.

Thanks for the recommendation, I was worried they would be missing some of my artists but they had 99% of my music. Can’t wait to ditch Spotify.
- Comment on Why can't people make ai's by making a neuron sim and then scaling it up with a supercomputer to the point where it has a humans number of neurons and then raise it like a human? 6 months ago:
We’ve got some really good theories, though. Neurons make new connections and prune them over time. We know about two types of ion channels within the synapse - AMPA and NMDA. AMPA channels open within the post-synapse neuron when glutamate is released by the pre-synapse neuron. And the AMPA receptor allows sodium ions into the dell, causing it to activate.
If the post-synapse cell fires for a long enough time, i.e. recieves strong enough input from another cells/enough AMPA receptors open, the NMDA receptor opens and calcium enters the cell. Typically an ion of magnesium keeps it closed. Once opened, it triggers a series of cellular mechanisms that cause the connection between the neurons to get stronger.
This is how Donald Hebb’s theory of learning works. en.wikipedia.org/wiki/Hebbian_theory?wprov=sfla1
Cells that fire together, wire together.

Actually, neuron-based machine learning models can handle this. The connections between the fake neurons can be modeled as a “strength”, or the probability that activating neuron A leads to activation of neuron B. Advanced learning models just change the strength of these connections. If the probability is zero, that’s a “lost” connection.
Those models don’t have physical connections between neurons, but mathematical/programmed connections. Those are easy to change.

I’ve been quoting Jordan Peterson for years?! Ahhh fuck.

Actually, we’ve got some pretty sophisticated models of neurons. en.wikipedia.org/wiki/Blue_Brain_Project?wprov=sf…
See my other comment for an example of how little we truly understand about neurons.

Even assuming we can model the same number of (simple machine learning model) neurons, it’s the connections that matter. The number of possible connections in the human brain is literally greater than the number of atoms in the universe.

It’s not a terrible idea by any means. It’s pretty hard to do, though. Check out the Blue Brain Project. en.wikipedia.org/wiki/Blue_Brain_Project?wprov=sf…

Heck, we barely know how neurons work. Sure, we’ve got the important stuff down like action potentials and ion channels, but there’s all sorts of stuff we don’t fully understand yet. For example, we know the huntingtin protein is critical to neuron growth (maybe for axons?), and we know if the gene has too many mutations it causes Huntington’s disease. But we don’t know why huntingtin is essential, or how it actually effects neuron growth. We just know that cells die without it, or when it is misformed.
Now, take that uncertainty and multiply it by the sheer number of genes and proteins we haven’t fully figured out and baby, you’ve got a stew going.

Honestly, I started with an Ender 3 for less than $200 and it’s just fine. You’ll have to calibrate and fight with it for a bit, but once you get it running it’s just fine.

I continue to feed my X4 addiction. Picked up the DLC during the Thanksgiving sale. I’m on my second play, about 35 hours in. Realized I’ve made a lot of mistakes, but that’s half the fun.
