No adverse health effects have been causally linked to 5G radiofrequency exposure at levels within international safety guidelines. Extreme claims, such as that 5G causes cancer or spreads disease, are without scientific basis, though some researchers call for continued monitoring of long-term non-thermal effects.

5G encompasses three distinct frequency bands with radically different performance characteristics. High-band mmWave 5G achieves multi-gigabit speeds but has very limited coverage, while low-band 5G may offer only marginally better speeds than 4G LTE, and can even underperform a strong 4G connection indoors.

VPNs encrypt internet traffic between a device and the VPN provider's server and mask the user's IP address from websites visited, but they do not make a user fully anonymous online, since the VPN provider itself can typically see the user's real traffic, and login-based tracking and browser fingerprinting still function normally.

Economic research on AI's labor market impact finds substantial task-level automation potential concentrated in certain occupations, but most studies project transformation and augmentation of existing jobs alongside creation of new roles, rather than the wholesale elimination of employment across the economy, a pattern consistent with previous major technological transitions.

Blockchain technology's core cryptographic ledger structure is highly resistant to certain kinds of tampering, but 'unhackable' overstates its real-world security. Numerous documented hacks and thefts totaling billions of dollars have occurred through smart contract bugs, exchange vulnerabilities, and consensus-level attacks on smaller networks, none of which the base blockchain design prevents.

Modern lithium-ion batteries in phones and laptops include charge controller circuitry that stops delivering current once full and prevents dangerous overcharging, though research shows sustained time spent at 100 percent charge and elevated heat can contribute modestly to faster long-term capacity degradation compared to charging in a more moderate range.

iOS and Android use app suspension and intelligent background management to minimize battery drain. Manually force-closing apps and reopening them consumes more CPU and RAM than leaving them in their suspended state.

Current large language models and AI systems generate fluent, sometimes convincingly human-like text by predicting statistically likely word sequences learned from training data, and there is no scientific consensus or empirical evidence that these systems possess subjective experience, self-awareness, or sentience in any sense comparable to conscious biological minds.

The claim that deepfakes are completely impossible to detect is an overstatement: automated detection tools exist and continue to improve, but the gap between deepfake generation and detection remains significant, and humans alone are poorly equipped to identify modern deepfakes reliably.

Deleting a file normally only removes its reference from the file system's index while the underlying data remains on the storage medium and recoverable with common forensic software, and true data destruction requires overwriting, cryptographic erasure, or physical destruction rather than the standard delete or recycle bin emptying process.

HDMI is a digital interface in which signal quality is binary: it works or it does not. Any cable that meets the required specification carries identical picture and sound information. Expensive cables do not transmit 'better' 1s and 0s.

Fully autonomous vehicles that can operate anywhere, in any condition, without human oversight are not yet commercially available at scale. Current deployed systems, including robotaxi services, generally operate within geofenced areas under specific conditions and regulatory classifications well short of full, unrestricted autonomy.

Higher display refresh rates provide real, measurable benefits for motion clarity and input responsiveness, particularly in fast-paced gaming, but the benefit diminishes and eventually becomes imperceptible or irrelevant beyond certain thresholds for many use cases, and other display factors, including resolution, color accuracy, and panel type, often matter more for typical viewing.

Incognito or private browsing mode prevents a browser from saving local history, cookies, and site data on the device used, but it does not hide browsing activity from internet service providers, employers, schools, or the websites visited themselves, making it far less anonymous than commonly assumed.

Apple Mac computers can be infected with malware, and security researchers have documented a growing volume of Mac-targeting malware over the past decade, even though historically lower market share made Macs a less frequent target compared to Windows, a gap that has narrowed considerably.

Modern smartphones use flash memory for data storage, which is not affected by ordinary consumer magnets the way older magnetic storage media like floppy disks and cassette tapes were, though very powerful specialized magnets can still interfere with certain phone hardware components like compasses or, in some models, disable magnetically triggered features.

Hard disk drives store data magnetically and can be wiped by degaussing. SSDs use electronic flash memory cells and have no magnetic media. A magnet, even a strong one, cannot erase or damage SSD storage.

Adding more CPU cores does not automatically make a computer faster for all tasks. Performance gains from additional cores depend on whether software is specifically designed to run multiple operations in parallel; many everyday tasks remain limited by single-core performance, and some workloads see little to no benefit from extra cores.

Image quality depends on multiple factors beyond megapixel count, including sensor size, individual pixel size, lens quality, and image processing software, and packing more megapixels onto a small sensor, as in many smartphones, can reduce per-pixel light capture and image quality in low light rather than improving it.

Signal bars show signal strength between your phone and the nearest tower, but data speed and reliability also depend on network congestion, frequency band, and interference. Full bars on a congested tower can deliver slower speeds than fewer bars on a clear 5G connection.

Studies commissioned by aviation regulators found no verified cases of a commercial aircraft accident caused by a passenger's personal electronic device, and both the FAA and EASA relaxed rules in 2013 to allow most devices to remain on throughout flight, though cellular signals are still restricted to prevent ground network interference rather than flight safety risk.

Incognito mode provides local privacy by not saving history to the device. It does not encrypt traffic, hide the user's IP address, or prevent external parties from seeing browsing activity. True anonymity requires additional tools such as a VPN or Tor.

Quantum computers do not yet break all current encryption, and claims that they render all cybersecurity obsolete overstate both the current state of quantum hardware and the scope of cryptographic vulnerability. Quantum computers pose a specific, well understood future threat to certain types of encryption, while other cryptographic methods are already believed resistant, and practical, large-scale quantum code-breaking has not yet been achieved.

Automated or semi-automated accounts used to artificially amplify messages, manipulate trending topics, and create false impressions of widespread public support.
