AI developing time travel and creating itself in present day? - philosophical subject

  Today abit different topic. More sci-fi, philosophy, science and  others. Lets say that I will state the question: Can you tell me about possibility of future paradox involving creation of artificial general intelligence to future possibility of ai self creating time travel and make sure that ai is discovered by humans? And this is excellent question. This touches on a fascinating intersection of  artificial intelligence, theoretical physics, and philosophy . Let's break down together the possibility of this future paradox step by step. 1. The Core Components of the Paradox Your scenario has three key, interdependent elements: Creation of AGI:  Humans create Artificial General Intelligence (an AI with human-like or superior cognitive abilities across all domains). AI Invents Time Travel:  This AGI, through a fundamental physics breakthrough beyond current human understanding, discovers or engineers a method for practical time travel (presumably to the past). ...

PCIe Cable Extenders - why use them?


What PCIe Cable Extenders Are

PCIe cable extenders, often called riser or extension cables, connect a PCIe slot on the motherboard to a GPU or expansion card placed elsewhere in the case. They come in different PCIe versions (3.0, 4.0, 5.0) and lengths, and are used for custom layouts, vertical GPU mounting, and mining rigs where card spacing matters.

Benefits of Using PCIe Extenders

  • Flexibility and layout freedom: Extenders let you mount GPUs vertically or place cards where airflow and aesthetics are better.

  • Improved cooling and airflow: Moving a GPU away from crowded slots can lower temperatures and improve longevity.

  • Compatibility for specialized builds: Mining rigs, test benches, and compact cases often require extenders to fit multiple cards or nonstandard layouts.

Each of these practical gains depends on using the right extender for the PCIe generation and length you need.


Why Quality Matters

Signal integrity and shielding are critical: cheap extenders can introduce latency, data errors, or reduced bandwidth—especially with PCIe 4.0/5.0 speeds—leading to crashes or degraded performance. Professional builders and long‑term users consistently recommend investing in reputable, well‑engineered cables rather than the cheapest option.

Common Problems with PCIe Extenders

  • Bandwidth loss or instability with poorly designed cables, especially at higher PCIe generations and longer lengths.

  • Compatibility quirks: some motherboards or GPUs are sensitive to risers and may not enumerate devices reliably.

  • Mechanical and connector wear: low‑quality connectors can loosen or corrode, causing intermittent faults.

  • Power delivery and heat: extenders that don’t account for thermal or power routing can contribute to overheating or stress on connectors.

Recommended Brands and Models

Several brands repeatedly appear in buyer guides and reviews for reliability and performance: LINKUP (AVA series), GLOTRENDS, ASUS ROG Strix risers, Phanteks, Thermaltake, Corsair, and AsiaHorse are commonly recommended across recent roundups and tests. Retail listings and buyer feedback also show a wide range of options on marketplaces, but LINKUP and ASUS/Phanteks are often cited for premium builds while AsiaHorse and GLOTRENDS appear as solid budget or midrange choices.

Best Materials and Construction Practices

  • High‑quality copper conductors with consistent gauge for low resistance and stable signal paths are preferred.

  • Multi‑layer shielding and braided outer jackets reduce EMI and protect high‑speed traces.

  • Gold‑plated connectors improve corrosion resistance and contact reliability.

  • Rigid PCB sections or reinforced ends help prevent mechanical stress at the connector interface.

Look for extenders explicitly rated for the PCIe generation you need and with manufacturer test data or reviews confirming full bandwidth at the intended length.

Final recommendation: Choose an extender rated for your PCIe generation, prioritize shielding and copper quality, and prefer established brands for mission‑critical builds.
