  • We are in a time where a single invention can rarelt be great. For technological development you need thousands of small inventions, each that use previous technological breakthrough through decades of research. And even great things we have, are just refinement and miniaturization of things we already had.

    But if a single thing had to be said, I would say mRNA vaccines. Covid vaccines saved milions of lives, were developed in record times, and their technology could be used for HIV or even antitumoral vaccines.


  • And let’s not forget that fueling your car requires a tank, a decently sized pump and 2 minutes of your time. A quick charge will hopefully charge your battery to 80% in 30 minutes, while giving you less km and running 300kW of power through hefty cables and big transformers, consuming the amount of energy that a family house consumes in a few days.

    (And yes, battery manufacturing and disposal consume enormous amount of resources)

    Electric and gas have different situations in which they shine. Gas/diesel engines are just a bunch of steel and some control chips, optimized in more thana century of technological development if we couls develop carbon neutral fuel, electric cars would not be needed. Unfortunately, it woulf be difficult to do at scale of current fuel consumption. More (electric, battery-less) public transport, less road goods transportation, more nuclear, electric for vehicles that move 100% of the time (delivery and logistic vehicles) and carbon-free fuel for other kinds of vehicles (personal transportation) is a good balance, in my personal, ignorant, armchair opinion.













  • Added sugar is bad because we don’t need all the sugar we tipically consume.

    Eating fruits is healthier because you eat other nutrients (such as vitamins) and fibers that fill you faster make you eat less (while providing other benefits to your gastrointestinal system). A pure friot juice is more filling, contains more nutrients and less calories than sugary water with fruit additives and colorants, because as other said pure sugar is pure energy but doesn’t have nutrients, only calories. If you consume very little it’s the same (only as in calories) as eating a larger amount of fruits, but the little part is the problem usually.

    Eating too much fruit is also unhealthy, and can still be diabetic, it’s just much harder, more expensive and less convenient to consume unhralthy amounts of food rather than sugar.
