Back in 1980 my parents got me a British ZX81 kit to assemble, with 1024 bytes of RAM. (I still have it buried in the closet along with my other antiques- AFAIK it still works.) It ran BASIC so slowly that you could actually read the code about as fast as it executed, so I was "forced" to learn assembly language. I was amazed by how fast it was- it ran a million operations in just a few seconds! (wow.) You had to start by writing a BASIC program:
10 REM AAAAAAAAAAAAAAAA
20 PRINT USR(16514)
Then you had to POKE each assembly instruction into the comment, starting at 16514 for the first "A". The comment line would slowly turn into "10 REM x&$bL;,$_)[vU7z#AAAAAAAA". The next line was 20 PRINT USR(16514) (printing out the return value from the BC register).
Saving any ZX81 program onto a cassette tape was excruciating- they recorded as several minutes of loud high-pitched screeching. Usually you needed to save them twice because it failed half the time. Then to load the program you had to cue the tape you had to find exactly where the start of the screeching was, rewind several seconds, play the tape, and only then could you hit enter on LOAD. (Otherwise LOAD got confused by the *click* noise when you pushed the play button on the tape player.)
You young people don't realize what an easy life you have.
I'll leave aside the fact that most of these "charities" are tax-avoidance scams, and would probably do the world a favor by not existing.
Bill Gates gives about 40 times as much money to charities as do the Koch brothers, who together have about the same amount of money as Gates. The Koch brothers, in turn, are about 25X as generous as all the Walmart heirs combined- 85% of whose donations come from Christy and 15% from Alice. Jim and Rob also each have their $35 billion and together they donate approx. $30,000 to charity each year- i.e. 4 ppm of their total income. If I make six figures and I toss a dollar at a homeless person, I've just donated 10 ppm.
In comparison, the LDS church for example receives approx. ten billion dollars in "donations" (i.e. tithes) per year- ostensibly for charitable purposes- but spends only fifty million for charity, an overhead of approx. 99.5%. The Gates Foundation has an "overhead" of 90% (meaning 90% of his wealth is stuffed in his mattress). Charities would benefit 20X more if Mormons sent their tithe payments directly to scum-of-the-earth Bill Gates!!!!
Corn ethanol is ridiculously inefficient. Sugar-based biofuels, by contrast, can have a quite good return and are actively used by developing countries in South America that don't have money to waste on things that don't make economic sense (but aren't used in the US because we have relatively little land able to grow sugarcane).
In short, it's more complex than either "all bio-fuels are good" or "all bio-fuels are evil". This shouldn't be a surprise -- few things are so simple.
Out of a sample size of ten million people, chances are very good that some of them will do very stupid things (and then claim they didn't).

My experience running SolidWorks through MasterCAM was very different.
Feed MasterCAM the specs on your machine and the part file, and what you got Just Worked. Clamp the workpiece and you could walk away.
