1. lots of innovation in ICE engines is getting close to production. Cleaner, more efficient etc. This is important even while the industry is moving to EVs.

2. Bambu Labs leapfrogged prosumer 3D printing by 5-10 years. Their printers are becoming the de-facto standard. This will enable all sorts of startups for the next decade.

3. Most iPhones now have a 3D scanner + AI-aided software to accurately scan your body and generate designs is becoming more mature. See also 2.

4. material sciences both new discoveries and new applications for 50 years old discoveries

Bambu leaped by 5 months at most. Everyone has high speed options now, with Prusa being notably last to ship. Speed isn't the only important factor, don't feed the Boat race.

Can you name some of the innovation happening in ICE vehicles? Just some terms I can search for would be appreciated. Thanks!

I wish that was "under the radar" instead of "subject of a giant embarrassing marketing push"

South Ameria has been using bio ethanol as a fuel for a while now, it's cheaper and uses crops, there are projects to bring that to North Amerixa and the rest of the world!

Doesn’t bio ethanol take more fossil fuel energy to create than it replaces?

I'm not very well versed in the subject but this should point you in the right direction!

> for average conditions one unit of fossil-fuel energy is required to create 8.3 energy units from the resulting ethanol

It seems they’re in a unique position because sugar cane grows there, is used in industry, and the leftovers that aren’t usable for anything else can be turned into fuel.

I had no idea Brazil has a unique bio ethanol industry, thanks for sharing.
