  • For what its worth , the cache locality of Vec<Box<Dyn trait>> is terrible in general, i feel like if youre iterating over a large array of things and applying a polymorphic function you’re making a mistake.

    Cache locality isnt a problem when youre only accessing something once though.

    So imo polymorphism has its place for non iterative-compute type work, ie web server handler functions and event driven systems.

    Lower testosterone is probably a big part of it. Look at 23 or 24 year old enhanced bodybuilders. they look like theyre 35. For whatever reason peoples T levels have been going down about 1 percent per year for the last 50 years. Its bound to have an effect.






  • there were kind and hard working slave owners too. the institution itself is bad.

    realestate is simply the best and safest investment you can make in most of the civilized world today, in the same way that owning land and buying slaves to work it was the best investment 300 years ago.

    At the end of the day its just waste. If money spent on housing isnt going towards making more and better housing you end up with a choke in supply that raises the price of housing, which hurts the efficiency of society as a whole .

    Maybe if renting is only allowed for the party that built the house, it has to be rent to own, and is only allowed for say, 50 years after its construction. Have building codes to ensure it’ll be solid for a long time. With that investing in realestate could be both profitable and societally beneficial.
