It seems that Sefer toras can't be used for torah readings/alias(since nobody uses them for it and the amazing facts and feats book mentions a machine made Sefer can't be used. But Why cant a Sefer torah be written by a machine? If it's about lishma my pressing the start button should be good enough no?
1Could pushing a button be construed as Derekh Ketiva? Writing with you left hand (if you are a righty) is also invalid– Double AA ♦Jul 3, 2018 at 18:52
@Double AA That's a good point though I could hear a argument that pushing a button with your right hand works.– OrionJul 3, 2018 at 19:03
See this lengthy exposition by R. Yitzchak Abadi (no. 4) which particularly relates to the silk-screen process.– OliverJul 3, 2018 at 19:35
The Taz discusses using the a printing press,this is a very big discussion,if you can get your hands on a Yesodei Yeshurun on weekday davening he brings all opinions regarding this– samJul 3, 2018 at 19:55
Rav Abaidis way is a bit diff than a printing press since by his you push the ink through the silk sceeen,by a printing press the letters are formed already– samJul 3, 2018 at 19:57
Rambam list some things which would not give a Torah Scroll not a drop of sanctity and would be like a printed book:
If someone who wrote it is an Apikores or any other type of prohibited person. If someone wrote it without concentrating on Divine names.
שכתבו אפיקורוס או כיוצא בו משאר פסולין
שכתב האזכרות בלא כוונה
Computers seem to fall under that category.
In Kerisos 19b it is explained: Machshava is when someone thinks to do something, kavana is when someone is doing something for X.
You may have kavana with the button, but the computer doesn't.
"Computers seem to fall under that category" - I don't see how it fits the first category. A computer has no emotions (well, maybe "Alexa", Siri and that GPS woman do.) As for lack of concentration, would programming a computer to write the names in their proper position constitute kavanah? What about if one stopped the program just prior to the computer writing the name and then was there to witness the computer write the Divine names?– DanFJul 3, 2018 at 19:30
I was also thinking a computer is certainly not a human, so it can't be kosher or pasul to write @DanF Jul 3, 2018 at 19:34
@shmuel my pen isn't human but its allowed to write. The point would be that the machine like a pen or the rest of my property is a extension of me– OrionJul 4, 2018 at 1:35
If we could extented someone’s hand why do try to be ‘yotze’ with writing a letter in the Torah, as apposed to having someone else do it. (Unless we de?...) @orion Jul 4, 2018 at 2:42
