<font color="blue"> Most all of the "digicams" are indoor cameras. </font>
Some are, some are not, just like film cameras.
<font color="blue"> They lack the strength for hard use and are sensitive to cold and heat and moisture. </font>
Some are and some are not. I've used my digital camera at temps below 0F and above 100F without a problem. You can also buy underwater cases for digital cameras. A coworker took his Olympus C750 skin diving. Took great pictures.
<font color="blue"> They also consume batteries at prodigious rates. </font>
Again, some do and some do not. Some film cameras require batteries as well. Even film cameras that do not use batteries can have problems with heat, cold and dust.
<font color="blue"> I cannot see how a few thousand or even a few million pixels will ever be comparable to the trillions of light sensitive molelcules in film. </font>
Digital is not for everyone nor every photographer. Many people can not tell the difference between a print from film and a print from a digital camera. For those people who can, they should stay with film.
<font color="blue"> All digital cameras use an algorythem to compute the picture and "smooth" and fill in the missing data (that which is being photographed) ie, some of what you see in a digi pic is fabricated by a chip. </font>
True, but if you can not tell the difference the issue is moot.
You've mentioned several downsides to digital cameras. Film cameras have their own, albeit different, downsides, e.g., not knowing how good the picture is until the film is developed, having to develop all the pictures on a roll of film, the cost of development, etc. As Sly and The Family Stone sang, "Different strokes for different folks."
