> Modern transistors, which function as a computer’s brain cells
Who's the target audience for this analogy? If you understand what a brain cell is then you probably know what a transistor is too. I would bet that more people know what a transistor is than what a brain cell is.
- artemonster 7y agoThe whole article is like this (facepalm)
- dang 7y agoMaybe so, but could you please stop posting unsubstantive comments to Hacker News?
- capableweb 7y agoYou don't need to know the details of a brain cell to get the analogy. If I say "transistor" to my mom, she wouldn't be able to tell me what it is. If I say "It's like the brain cells for the computer", she would probably understand that "Ah, so a computer has many transistors that helps it think", which seems good enough for an article with a broad audience. > I would bet that more people know what a transistor is than what a brain cell is I'm happy to take you up on that bet, but it depends on what bubble you ask. In San Francisco/Silicon Valley, that's probably true, but outside any high-tech bubbles, more people know that we have brain cells in our heads, than we have transistors in our computers, I'm fairly sure.
- Someone 7y agoI would take that bet, too. If you say “transistor” to non-technical people over 50 or so, they more likely would think of small portable radios (https://en.m.wikipedia.org/wiki/Transistor_radio https://en.m.wikipedia.org/wiki/Transistor_radio). To them, and many others, computers don’t have transistors, they have chips. They _might_ know the transistor replaced vacuum tubes, but I doubt many would be able to tell what function either had, or be able to point out the transistors inside such a radio.
- pbhjpbhj 7y agoIs that a USA/North America thing, based on calling radio sets "transistor radios"? Here in the UK we had "the wireless", and I'm confident that my parents - late 70s - who were the generation of first domestic computer ownership in the UK would associate "transistor" primarily with computers.
- romwell 7y agoDefinitely not just a USA thing, "transistor" also meant "transistor radio" in Russian back in the day. (E.g. this song from 1982: https://learnsongs.ru/song/dinamik-na-plyazhe-pleshchet-volna-68477 https://learnsongs.ru/song/dinamik-na-plyazhe-pleshchet-voln...)
- neeleshs 7y agoSame in India!
- z3t4 7y agoA CPU do not think. It follows precise instructions.
- newsbinator 7y agoAnd what about a human brain?
- knolax 7y agoBut does your mother read Wired?
- capableweb 7y agoFor sure not, being from not-the-US, she has most likely never heard of "Wired"
- VierScar 7y agoI've been told I have two of them
- martin-adams 7y agoSo n=2 of Moore’s law for you. Keep going.
- cs02rm0 7y agoI would bet that more people know what a transistor is than what a brain cell is. No chance. Everyone knows what a brain cell is, to some extent. Even people who have too few to rub together don't really feel like they know what a transistor is after reading the Wikipedia page for them, twice...
- jl2718 7y agoI used to know what a transistor was. And then we shrunk them to the point where they are no longer the same thing and yet they are still a thing, so I don't know what they are anymore.
