Winning the world 100m is just about running faster. A Nobel prize is won if you think just a little bit harder... Pushing the envelope has always been heroically hard and always will be.

SpaceX aren't pushing any envelopes. They're just doing what has already been done for decades, but for a lower price.

Edit: Instead of downvoting, how about replying? There are only 3 clauses above, so you can just say which one of those clauses is wrong and why.

"SpaceX aren't pushing any envelopes. They're just doing what has already been done for decades, but for a lower price."

Logical fallacy. The fact that the differences in output are only quantitatively different doesn't mean that the differences in process aren't qualitatively different.

Do you consider the IBM PC something that pushed the envelope? Sometimes disrupting an industry by making its products available at a dramatically lower cost is just as much a push to the envelope in the real world as a new discovery. (Other examples include firms like 23andme etc)

Look at the comment I was replying to[1]. The author of that comment was using "pushing the envelope" to mean running faster in the 100m dash or winning a Nobel prize. Disrupting an industry, as SpaceX are doing, is extremely worthwhile, but no one has ever argued that the IBM PC was some sort of breakthrough in computing, or represented progress in programming techniques (quite the opposite in fact, it was cheap and took many shortcuts, resulting in the horrible situation we have in computing today).

At the time, the IBM PC was very impressive compared to the other microcomputers available.

The way I remember it, the main thing it had going for it was that 'IBM' tag.

Its graphics were worse than that of the 4 year old Apple II, its speed was only a little higher (certainly way of from what the 1:4.77 clock speed ratio would make you think; both ran at around 1 MIPS).

Yes, it handled more than 64k RAM and was 16 bit-ish, but very impressive? Not in my memory.

The original 5150 PC had a wonderful keyboard. We'd consider it very heavy and loud today (each key had a spring beneath it, and made a very audible click when pressed), but compared to the other keyboards at the time, it was easily the best.

I wonder if we'll look back at this a few years from now and say, "At the time, the iPad was very impressive compared to the other tablets available."

1. Yes, it is pushing envelopes. 2. Never been done by private industry. 3. Radically lower price.

Arianespace is a private company (admittedly with some government shareholders, but EADs is also a large shareholder) and it has been operating commercially since 1980 having done hundreds of launches:

Usain Bolt isn't pushing any envelopes. He's just doing what has already been done for decades, but at a higher speed.

Entirely true. Not sure of the relevance.

Seriously though, SpaceX isn't Usain Bolt, it's... Fabio Cerruti (of Italy, fifth-place getter in the first heat of the men's 100m at the 2008 Olympics). He ran 100m in 10.49 seconds, which is very impressive, but nothing that hasn't been done before.

OK, enough athletics analogies.

Sorry if it wasn't clear. To my understanding, "pushing the envelope" means just going a little bit further than anyone else has gone before. You obviously have a different definition.

So, if they are doing what has been done before for a lower price, then they are pushing the price/performance envelope?

The second two clauses contradict the first..
