I have no doubt the'll start building chargers but I think the ramp up will be slower and the power levels will be lower than what people think. Most cars can't even charge at 350kW because their batteries are too small. You'd damage the batteries.

I have no doubt that they are serious and ambitious, but they are so far behind Tesla that it‘s not likely that they will catch up until 2020. Also, they are planning to place their fast chargers only 120 Km apart to accommodate for a wider range of vehicles, which puts them at a disadvantage too.

I don't think it will take more than a couple of years for well-maintained superchargers to be ubiquitous, and that's if you give away the power for free with government subsidies. If you charge customers for the energy, it might happen even faster.

Or about 1/7th of a windmill.

So far I have heard a lot of announcements about great cars and great charging networks from these companies but nothing they have actually done gives me any confidence.

People also said that the other car makers will switch the electric and start building electric cars in mass easily and quickly. So far however most of these projects have seen delays and other problems.

I would also say that all the 'lower' level chargers will benefit Tesla equally to everybody else, so its no intensive to buy a non-Tesla.

It is why teslamotors.com is now tesla.com

CHAdeMO is the better standard for fast charging, IMHO, since it allows bidirectional charging.

They choose not to make such an update though...
