# Key Points from #hplusroadmap IRC Discussion

• Sci-Hub (http://sci-hub.cc) has become the dominant tool for accessing paywalled academic papers, effectively replacing older solutions like "paperbot" that researchers previously relied on.

• Laser projector technology has undergone dramatic price reduction, falling from over $1,000,000 to under $10,000, with Casio's lamp-free models highlighted for their 20,000-hour lifetimes and used models available for as little as $100-600.

• Users discussed how proper cooling of LED components in projectors can significantly extend their operational lifespan beyond manufacturer specifications, representing an important technical insight for hardware longevity.

• Kanzure outlined a sophisticated concept for an "electronically-directed polymerase" system using CMOS arrays with surface-immobilized polymerases on chips, enabling high-throughput testing of mutant polymerases in compartmentalized emulsion droplets.

• The proposed polymerase evolution system would incorporate inkjet printing for material deposition into emulsion droplets and physical addressing capabilities to allow selective extraction of successful variants through micropipetting at specific coordinates.

• A presentation titled "Introduction to Brains as Emergent Turing Machines" was mentioned, consisting of 83 slides, though it was noted that the application sections remained incomplete.
