“The greater the speed required of us in the digital world – and speed does matter, but never at the expense of accuracy or fairness or anything which would imperil trust – the more we should be honest about the tentative nature of what is possible.”

André Delambre (David Hedison) to his wife Hélène
The Fly (1958)
Context: I can transport matter — anything — at the speed of light, perfectly. Of course this is only a crude beginning, but I've stumbled on the most important discovery since man sawed off the end of a tree trunk and found the wheel. The disintegrator-integrator will change life as we know it. Think what it means. Anything, even humans, will go through one of these devices. No need for cars or railways or airplanes, even spaceships. We'll set up matter-receiving stations throughout the world, and later the universe. There'll never be famine. Surpluses can be sent instantaneously at almost no cost, anywhere. Humanity need never want or fear again. I'm a very fortunate man, Hélène.

Context: Charles B. Spahr, Walter A. Wyckoff, Mrs. John Van Vorst and Miss Marie Van Vorst, I. K. Friedman and A. M. Simons have given us some idea of the conditions among the poorest class of laborers in various industrial centers over the country. Jacob A. Riis, Ernest Poole, and Mrs. Lillian Betts have given us most sympathetic descriptions of poverty among the people of the tenements. Flynt and others have given us impressionistic stories of tramps, vagrants, and mendicants. They bring before our very eyes, through books and magazines, stories of needless deaths from insanitary conditions, of long hours of work, of low pay, of overcrowded sweatshops, of child labor, of street waifs, of vile tenements, of the hungry and the wretched. All these books and articles are extremely valuable and useful, but if anything is to be done about the matter, we should begin as soon as possible to know the extent of these conditions and the causes which bring such terribly serious misery and wretchedness into the world.

While widely quoted as an example of failed predictions about technological progress and attributed to Lardner, there are no known citations of this line prior to 1980 and it does not seem to appear in his published works. It may result from the conflation, through imperfect memory and oral transmission, of reference to three separate concepts: the real, and at the time new, danger of suffocation by engine combustion gasses in tunnels (and in particular an 1861 incident http://www.engineering-timelines.com/scripts/engineeringItem.asp?id=202 in the Blisworth Tunnel), the hypothetical (and unfounded) fear of suffocation by vacuum in a speculated system of trains propelled by pneumatic force https://books.google.com/books?id=2Tc1AQAAMAAJ&lpg=PA261&ots=lL3eBeyoex&dq=lardner%20train%20speed%20suffocation&pg=PA261#v=onepage&q=Lardner&f=false, and Lardner's erroneous prediction of mechanical failure of trains in the Box Tunnel of the Great Western Railway from over-acceleration due to excess gradient.
